Inequality: the ‘defining issue of our day’?

Wes Streeting and Andy Burnham are seeking to become UK Prime Minister in a challenge to Keir Starmer. They have both responded to an essay by Tony Blair, former Labour Prime Minister, where he argued that current Labour policies were holding back business. But the essay never mentioned inequality. According to Burnham and Streeting, inequality and the related issue of poverty are fundamental to the crises facing society in western democracies. Countries’ economic success is typically measured in terms of growth in GDP. But when the benefits of growth go largely to those at the top of the income scale, while people on lower incomes struggle to make ends meet, this feeds resentment. Populist politicians stoke such resentment and offer simplistic solutions, such as protectionism, blaming outsiders and promising a return to better times.

But just what has happened to inequality over recent years and has poverty deepened? How are inequality and poverty affecting people’s lives and what is the impact on the economy? And what policies should governments follow to tackle the problem?

Income inequality

The chart shows UK inequality as given by the Gini coefficient, where 1 represents complete inequality, with one person earning the whole of national income and 0 represents perfect equality, with everyone earning the same. The higher the figure, therefore, the greater the inequality. As you can see, inequality is greatest when looking at original income – that is, income before taxes and benefits. Gross income includes benefits, and disposable income is income after both benefits and taxes. You can see that both benefits and taxes reduce inequality. When we take housing costs into account with the disposable income measure, however, inequality increases.

The chart shows that income inequality rose until the early 2000s, since when there have been only slight changes, although there has been a small decline recently.

The UK has higher income inequality than most high-income countries, although it is not as high as in the USA. It is sixth most unequal of the 38 OECD countries and the most unequal OECD member in Europe.

Globally, in 2025, the top 10% of the world’s population earned 53% of global income, while the bottom half earned just 8%. The reports listed below provide data and analysis on UK and global inequality.

Wealth inequality

When we turn to wealth, inequality in the UK is even greater. The richest 10% of households hold around 41% of wealth, while the poorest 50% hold just under 10%. The Gini coefficient is around 0.6. This has been drive by a rise in property and share prices and the system of inheritance whereby family wealth can accumulate over the generations.

Globally, the top 10% of the world’s population held 75% of global wealth in 2025, whereas the bottom 50% held just 2%. And a tiny group of people – the top 0.001% of the adult population (about 56,000 individuals) – held about 6% of global wealth, up from 4% in 1995. Such extreme wealth inequality has thus increased.

Inequality and poverty

There is no single measure of poverty. It could be measured in terms of basic needs. Here poverty would be where a person is unable to afford basic food, shelter, heating and lighting, clothing, footwear and basic toiletries. Normally, however, it is measured in relative terms. A typical measure, and one used by the Joseph Rowntree Foundation, is based on a proportion of median income. Poverty is defined as income below 60% of the median income, with deep poverty below 50% and very deep poverty below 40%.

In 2023/24, 14.2 million people were in poverty (20% of the population), of whom around 4.5 million were children. Of the 14.2 million, 6.8 million people (nearly half) were in very deep poverty,

Causes of poverty include one or more of the following: low skills or education, low pay, unemployment, inadequate benefits or a benefit system that is confusing or difficult to access, chronic sickness, disability, unavailability or cost of suitable housing, discrimination, a breakdown of personal relationships, substance abuse, abuse from others, a criminal record. Once in poverty, it becomes difficult to escape as people become deskilled, demotivated and judged by society.

But even if people are not earning less than 60% of median income, they can still struggle to escape inequality. Many people have low skills; many routine jobs are being replaced by automation or AI; many graduates face high debts; people struggle to get on the housing ladder; the rising cost of basic items dampens real incomes, especially of the low paid; people may face discrimination of various sorts; people do not have an option of joining a union in their workplace; people may have a large number of dependants.

The policy agenda

If inequality rises up the political agenda in the UK, especially with a potential leadership race in the Labour party, what might politicians focus on? The government has already done the following:

  • It has raised the minimum wage (the ‘National Living Wage’) substantially from £10.42 in 2023/24 to £11.44 in 2024/25, to £12.21 in 2025/26 and lowered the age limit from 23 to 21. There have been larger percentage rises for 18–20 year-olds and those under 18.
  • The two-child limit to the child benefit element in Universal Credit has been scrapped and so now parents are eligible for benefits for all children.
  • The Employment Rights Act has ended exploitative zero-hour contracts by providing rights to guaranteed hours.
  • It has expanded free school meal entitlements.
  • It has capped Universal Credit debt deductions at 15% of increased incomes (down from 25%) to help the poorest households retain more of their monthly income.
  • It has expanded free school meals and made more money available for free nursery place.
  • Landlords can no longer evict tenants for no reason; they must have a valid reason such as wanting to sell the property or severe rent arrears.
  • Landlords cannot increase rents more than once per year and tenants can appeal excessive or above-market rent increases to an independent tribunal.

But despite these policy measures, many claim that they will do too little to tackle inequality and poverty. Some on the left argue that taxes on property and other forms of wealth will be required to tackle wealth inequality. Others argue that more emphasis on education and training is necessary to provide workers with the skills to earn more in the labour market. Others argue for greater expenditure on public services.

Generally, however, measures to tackle inequality and poverty require government expenditure, which must be funded. This is why many on the centre left argue that economic growth is a necessary condition for any significant redistribution. It is, they argue, the best way of providing the tax revenue to fund redistribution.

Incentives and disincentives

Many on the right argue that redistributing incomes through higher taxes and benefits will act as a disincentive to work and to invest. As we argue in Essentials of Economics, higher income taxes could discourage people from working and investing; higher wealth taxes could discourage people from saving and investing.

The key to analysing these arguments is to distinguish between the income effect and the substitution effect of raising taxes. Raising income tax does two things.

  • It reduces disposable incomes. People therefore are encouraged to work more in an attempt to maintain their consumption of goods and services. This is the income effect. ‘I have to work more to make up for the higher taxes’, a person might say.
  • It reduces the opportunity cost of leisure. Since higher income taxes reduce take-home pay, an extra hour taken in leisure now involves a smaller sacrifice in consumption. Thus people may substitute leisure for consumption, and work less. This is called the substitution effect. ‘What is the point of doing overtime’, another person might say, ‘if so much of the overtime pay is going in taxes?’

The relative size of the income and substitution effects is likely to differ for different types of people. For example, the income effect is likely to dominate for those people with a substantial proportion of long-term commitments, such as those with families, with mortgages and other debts. They may feel forced to work more to maintain their disposable income. Clearly for such people, higher taxes are not a disincentive to work. The income effect is also likely to be relatively large for people on higher incomes, for whom an increase in tax rates represents a substantial cut in income.

The substitution effect is likely to dominate for those with few commitments: those whose families have left home, the single, and second income earners in families where that second income is not relied on for ‘essential’ consumption. A rise in tax rates for these people is likely to encourage them to work less.

Although high income earners may work more when there is a tax rise, they may still be discouraged by a steeply progressive tax structure. If they have to pay very high marginal rates of tax, it may simply not be worth their while seeking promotion or working harder.

What those on the centre and left argue is that tackling inequality and poverty requires more than just changing the tax and benefits system. What is required is policies that encourage greater upward social mobility, greater social cohesion and greater expenditure on infrastructure that will support the poor, such as greater expenditure on education and training, on support for very young children, on preventative healthcare, on social housing and on local public transport.

Youth unemployment and the post-pandemic peak

Unemployment in the UK reached its highest level in nearly five years at the close of 2025, according to new data from the Office for National Statistics. Figures show the unemployment rate rising to 5.2% in the three months to December, up slightly from 5.1% in the preceding quarter.

This marks the highest unemployment level since the pandemic, coinciding with a slowdown in wage growth and increasing speculation that interest rates may soon be lowered.

Youth unemployment

However, young people are taking the heaviest hit, with unemployment climbing to 16.1% among those aged 16 to 24. (Click here for a PowerPoint of the chart.) This is the highest level in more than a decade, including the spike seen during the pandemic. Economists largely attribute this trend to rising payroll costs, which they say are discouraging employers from offering entry level roles. Long-term youth unemployment is also worsening, with recent data showing that a growing share of unemployed young people have been out of work for over 12 months, highlighting deeper and more persistent barriers to re entry.

At the same time, although wages for those in work continue to grow faster than prices, the pace of wage growth is steadily slowing, adding further pressure on young people already facing the most challenging labour market conditions in years. According to ONS data, the annual growth in average weekly wages, excluding bonuses, slowed to 4.2% in the last three months of 2025. Private-sector wage growth eased to 3.4%, bringing it closer to the 3.25% rate that the Bank of England believes is consistent with its 2% inflation target.

The impact on interest rates

The Bank of England is watching the slowdown in the UK jobs market closely as it gauges when next to lower its interest rates. In February 2026, the Monetary Policy Committee voted to hold the base rate (Bank Rate) at 3.75%. However, the committee voted with a majority of 5-4, with four members voting to reduce the rate to 3.5%.

The Bank of England uses interest rates as a policy tool to control inflation, the rate at which general prices rise in the economy. The current rate of inflation of 3.4% is above the Bank of England’s target of 2%.

In addition to the split vote, some economists believe that the easing in pay growth makes it likely that Bank Rate will be cut at the next meeting on 19th March. Paul Dales, chief UK economist at Capital Economics, said the fall in wage growth ‘supports the idea that the Bank of England has at least a couple more interest rate cuts in its locker’. A decrease in interest rates will be welcomed by investors.

What is behind the increase in youth unemployment?

Young people always tend to be the most impacted by a downturn in hiring. But economists warned that the rise in youth unemployment was a sign that employers are being more cautious about hiring younger workers. Openings for low-skilled entry-level roles and for new graduates have dropped steeply. Many businesses have slowed hiring due to an increase in costs because of measures in Chancellor Rachel Reeves’s last two Budgets. Businesses claim that the combination of increases in employer National Insurance contributions and a rise in the minimum wage mean they are facing higher payroll costs.

Peter Dixon at the National Institute for Economic and Social Research said, ‘there are indications that younger workers in particular are being priced out of the market’, supporting the explanation that raising the minimum wage might also be disincentivising the hiring of young people.

The ONS reported that the retail and wholesale sector saw the biggest fall in the number of workers on company payrolls, with 65,000 jobs lost in the sector since January last year. Meanwhile, health and social work saw the biggest rise in payrolled workers of any sector, adding 39,000 jobs in the year to January. Financial analyst at AJ Bell, Danni Hewson, suggested that those leaving the retail sector were now entering healthcare, with both sectors employing large numbers of women. However, she also warned that a recent surge in investment in artificial intelligence could hit young people the hardest as it could result ‘in a scarcity of entry level posts’ (see the blog Will AI make the world less equal?.

Job vacancies

Job vacancy data across the UK indicates a significant cooling in labour demand. According to the latest ONS figures, vacancies fell from 736,000 in the three months to December to 726,000 in January, signalling continued weakening in hiring activity. According to the job search site, Adzuna, the number of vacant positions has dropped to its lowest level in five years, with job listings sliding 3% in January to 695,000, marking the first time vacancies have dipped below 700,000 since early 2021. Notably, graduate opportunities have fallen below 10,000 for the first time since Adzuna started tracking in 2016, underscoring the deepening challenges for new entrants to the workforce.

This downward trend in job openings extends patterns seen throughout late 2025, with vacancies down 16% from the previous January and nearly 20% lower than six months earlier. This coincides with a rise in unemployment to 5.2%, slower wage growth, and a growing concern that young people are disproportionately affected as hiring slows. As opportunities shrink, competition has intensified: there are now 2.4 jobseekers per vacancy, up from 2.27 in December, with the most sought-after roles including warehouse staff, healthcare support workers, lorry drivers, labourers and kitchen assistants.

How can the situation be improved?

Pat McFadden, Secretary for Work and Pensions, has commissioned the former Health Secretary Alan Milburn to lead a review into the causes of rising youth inactivity. There will be a particular focus on mental health issues that are pushing young people out of education and employment. This initiative responds to the growing number of young people not in education, employment, or training (NEETs), many of whom are now classified as inactive rather than unemployed. Some receive health-related benefits and are therefore not required to look for work, while others fall outside the benefits system entirely, making them harder to identify and support.

However, Pat McFadden said there was ‘more to do to get people into jobs’, and that tackling youth unemployment is a key government priority. He added that Labour was working to make it easier for young people to find and secure an apprenticeship, supported by a wider package of reforms. The reforms announced by McFadden include creating 50,000 additional apprenticeships. The government will also expand support for 350,000 people to move into work or training in sectors such as care and construction, with the risk of losing benefits if they refuse. They also include the provision of 55,000 state-funded, six-month work placements for the long-term unemployed.

While these measures are widely seen as necessary, campaign groups argue the government should go further by extending its ‘Youth Guarantee’ to cover all young people up to age 24, rather than ending at 22.

However, as Alice Martin, head of research at Lancaster University’s Work Foundation, notes, initiatives designed to help people return to the labour market have limited impact ‘if the jobs aren’t out there.’ Even graduates are finding that opportunities are scarce, and for those leaving education with few qualifications, the situation is even more challenging. Sectors such as retail, once a reliable source of first jobs, have been in long-term structural decline, a trend that is now accelerating and further narrowing the pathways available to young people entering the workforce.

The situation has prompted government discussions about postponing the planned rise in the minimum wage for 18- to 20-year-olds to address employers’ concerns and encourage more youth employment. However, on Wednesday, Keir Starmer stressed that Labour remains committed to its manifesto pledge to align the pay of younger workers with that of older employees. The Prime Minister confirmed that the promise to ‘remove the discriminatory age bands’ in the minimum wage system still stands, and that the increase scheduled for April will proceed as planned.

Starmer said ‘We’ve made commitments to young people in our manifesto, and we will keep to those commitments, including the commitment that we would make sure that the living wage and minimum wage will go up this April, which we can absolutely confirm to you will happen.’

Unemployment outlook

Multiple economic forecasts predict that unemployment will to continue to rise in 2026. The most frequently cited projection places the 2026 unemployment rate around 5.2%–5.5%. However, some economists expect businesses to regain confidence and begin hiring again later in the year, supporting a gradual stabilisation in job markets.

Yet risks remain significant: if that recovery fails to materialise, unemployment could edge toward 6% by the end of the year, with forecasts from JP Morgan suggesting unemployment may reach 2 million in the first half as firms delay recruitment following the recent rise in the employers’ National Insurance rate. This environment is proving especially challenging for young people, with early career opportunities among the first to disappear and delayed entry into work potentially limiting long-term earnings and progression.

As hiring becomes more cautious and entry-level roles tighten, the path into the labour market risks becoming narrower, underscoring the need for policies and conditions that support both employer confidence and opportunities for new entrants.

Raising the minimum wage: its effects on poverty and employment

The first Budget of the new UK Labour government was announced on 30 October 2024. It contained a number of measures that will help to tackle inequality. These include extra spending on health and education. This will benefit households on lower incomes the most as a percentage of net income. Increases in tax, by contrast, will be paid predominantly by those on higher incomes. The Chart opposite (taken from the Budget Report) illustrates this. It shows that the poorest 10% will benefit from the largest percentage gain, while the richest 10% will be the only decile that loses.

But one of the major ways of tackling inequality and poverty was raising the minimum wage. The so-called ‘National Living Wage (NLW)’, paid to those aged 21 and over, will rise in April by 6.7% – from £11.44 to £12.41 per hour. The minimum wage paid to those aged 18 to 20 will rise 16.3% from £8.60 to £10.00 and for 16 and 17 year-olds and apprentices it will rise £18% from £6.40 to £7.55.

It has been an objective of governments for several years to relate the minimum wage to the median wage. In 2015, the Conservative Government set a target of raising the minimum wage rate to 60 per cent of median hourly earnings by 2020. When that target was hit a new one was set to reach two-thirds of median hourly earnings by 2024.

The Labour government has set a new remit for the minimum wage (NLW). There are two floors. The first is the previously agreed one, that the NLW should be at least two-thirds of median hourly earnings; the second is that it should fully compensate for cost of living rises and for expected inflation up to March 2026. The new rate of £12.41 will meet both criteria. According to the Low Pay Commission, ‘Wages have risen faster than inflation over the past 12 months, and are forecast to continue to do so up to March 2026’. This makes the first floor the dominant one: meeting the first floor automatically meets the second.

How effective is the minimum wage in reducing poverty and inequality?

Figure 1 shows the growth in minimum wage rates since their introduction in 1999. The figures are real figures (i.e. after taking into account CPI inflation) and are expressed as an index, with 1999 = 100. The chart also shows the growth in real median hourly pay. (Click here for a Powerpoint.)

As you can see, the growth in real minimum wage rates has considerably exceeded the growth in real median hourly pay. This has had a substantial effect on raising the incomes of the poorest workers and thereby has helped to reduce poverty and inequality.

The UK minimum wage compares relatively favourably with other high-income economies. Figure 2 shows minimum wage rates in 12 high-income countries in 2023 – the latest year for which data are available. (Click here for a PowerPoint.) The red bars (striped) show hourly minimum wage rates in US dollars at purchasing-power parity (PPP) rates. PPP rates correct current exchange rates to reflect the purchasing power of each country’s currency. The blue bars (plain) show minimum wage rates as a percentage of the median wage rate. In 2023 the UK had the fourth highest minimum wage of the 12 countries on this measure (59.6%). As we have seen above, the 2025 rate is expected to be 2/3 of the median rate.

Minimum wages are just one mechanism for reducing poverty and inequality. Others include the use of the tax and benefit system to redistribute incomes. The direct provision of services, such as health, education and housing at affordable rents can make a significant difference and, as we have seen, have been a major focus of the October 2024 Budget.

The government has been criticised, however, for not removing the two-child limit to extra benefits in Universal Credit (introduced in 2017). The cap clearly disadvantages poor families with more than two children. What is more, for workers on Universal Credit, more than half of the gains from the higher minimum wages will lost because they will result in lower benefit entitlement. Also the freeze in (nominal) personal income tax allowances will mean more poor people will pay tax even with no rise in real incomes.

Effects on employment: analysis

A worry about raising the minimum wage rate is that it could reduce employment in firms already paying the minimum wage and thus facing a wage rise.

In the case of a firm operating in competitive labour and goods markets, the demand for low-skilled workers is relatively wage sensitive. Any rise in wage rates, and hence prices, by this firm alone would lead to a large fall in sales and hence in employment.

This is illustrated in Figure 3 (click here for a PowerPoint). Assume that the minimum wage is initially the equilibrium wage rate We. Now assume that the minimum wage is raised to Wmin. This will cause a surplus of labour (i.e. unemployment) of Q3 – Q2. Labour supply rises from Q1 to Q3 and the demand for labour falls from Q1 to Q2.

But, given that all firms face the minimum wage, individual employers are more able to pass on higher wages in higher prices, knowing that their competitors are doing the same. The quantity of labour demanded in any given market will not fall so much – the demand is less wage elastic; and the quantity of labour supplied in any given market will rise less – the supply is less wage elastic. Any unemployment will be less than that illustrated in Figure 3. If, at the same time, the economy expands so that the demand-for-labour curve shifts to the right, there may be no unemployment at all.

When employers have a degree of monopsony power, it is not even certain that they would want to reduce employment. This is illustrated in Figure 4: click here for a PowerPoint (you can skip this section if you are not familiar with the analysis).

Assume initially that there is no minimum wage. The supply of labour to the monopsony employer is given by curve SL1, which is also the average cost of labour ACL1. A higher employment by the firm will drive up the wage; a lower employment will drive it down. This gives a marginal cost of labour curve of MCL1. Profit-maximising employment will be Q1, where the marginal cost of labour equals the marginal revenue product of labour (MRPL). The wage, given by the SL1 (=ACL1) line will be W1.

Now assume that there is a minimum wage. Assume also that the initial minimum wage is at or below W1. The profit-maximising employment is thus Q1 at a wage rate of W1.

The minimum wage can be be raised as high as W2 and the firm will still want to employ as many workers as at W1. The point is that the firm can no longer drive down the wage rate by employing fewer workers, and so the ACL1 curve becomes horizontal at the new minimum wage and hence will be the same as the MCL curve (MCL2 = ACL2). Profit-maximising employment will be where the MRPL curve equals this horizontal MCL curve. The incentive to cut its workforce, therefore, has been removed.

Again, if we extend the analysis to the whole economy, a rise in the minimum wage will be partly passed on in higher prices or stimulate employers to increase labour productivity. The effect will be to shift the (MRPL) curve upwards to the right, thereby allowing the firm to pass on higher wages and reducing any incentive to reduce employment.

Effects on employment: evidence

There is little evidence that raising the minimum wage in stages will create unemployment, although it may cause some redeployment. In the Low Pay Commission’s 2019 report, 20 years of the National Minimum Wage (see link below), it stated that since 2000 it had commissioned more than 30 research projects looking at the NMW’s effects on hours and employment and had found no strong evidence of negative effects. Employers had adjusted to minimum wages in various ways. These included reducing profits, increasing prices and restructuring their business and workforce.

Along with our commissioned work, other economists have examined the employment effects of the NMW in the UK and have for the most part found no impact. This is consistent with international evidence suggesting that carefully set minimum wages do not have noticeable employment effects. While some jobs may be lost following a minimum wage increase, increasing employment elsewhere offsets this. (p.20)

There is general agreement, however, that a very large increase in minimum wages will impact on employment. This, however, should not be relevant to the rise in the NLW from £11.44 to £12.41 per hour in April 2025, which represents a real rise of around 4.5%. This at worst should have only a modest effect on employment and could be offset by economic growth.

What, however, has concerned commentators more is the rise in employers’ National Insurance contributions (NICs) that were announced in the Budget. In April 2025, the rate will increase from 13.8% to 15%. Employers’ NICs are paid for each employee on all wages above a certain annual threshold. This threshold will fall in April from £9100 to £5000. So the cost to an employer of an employee earning £38 000 per annum in 2024/25 would be £38 000 + ((£38 000 – £9100) × 0.138) = £41 988.20. For the year 2025/26 it will rise to £38 000 + ((£38 000 – £5000) × 0.15) = £42 950. This is a rise of 2.29%. (Note that £38 000 will be approximately the median wage in 2025/26.)

However, for employees on the new minimum wage, the percentage rise in employer NICs will be somewhat higher. A person on the new NLW of £12.41, working 40 hours per week and 52 weeks per year (assuming paid holidays), will earn an annual wage of £25 812.80. Under the old employer NIC rates, the employer would have paid (£25 812.80 + (£25 812.80 – £9100) × 0.138) = £28 119.17. For the year 2025/26, it will rise to £25 812.80 + ((£25 812.80 – £5000) × 0.15) = £28 934.72. This is a rise of 2.90%.

This larger percentage rise in employers’ wage costs for people on minimum wages than those on median wages, when combined with the rise in the NLW, could have an impact on the employment of those on minimum wages. Whether it does or not will depend on how rapid growth is and how much employers can absorb the extra costs through greater productivity and/or passing on the costs to their customers.

Big Mac wages

At least once a year The Economist publishes its ‘hamburger standard’ exchange rates for currencies. It is a light-hearted attempt to see if currencies are exchanging at their purchasing-power parity rates. The test is the price at which a ‘Big Mac’ McDonald’s hamburger sells in different countries!

According to this simplified version of the purchasing-power parity theory, exchange rates should adjust so that a Big Mac costs the same in dollars everywhere (see Economics 8th edition Box 25.4).

These Big Mac exchange rates can be used to compare various prices and incomes between countries. The article linked below from The Guardian compares minimum wages between European countries in Big Mac terms.

There are 25 countries across Europe which have minimum wages. A clear pattern of minimum wage rates can be seen: although actual exchange rates understate the purchasing power of incomes in poorer European countries compared to richer ones, minimum wages, even in purchasing-power standard terms, are still higher in the richer countries.

Luxembourg’s minimum wage buys you just about three Big Macs in an hour, while most of northern Europe (and France) between 2–2.5 Big Macs. Moving south, the minimum wage nets about one Big Mac an hour. As we progress east, it begins to cost more than an hour of work on the minimum wage in order to afford a Big Mac.

Of course, there are other factors determining the dollar price of a Big Mac other than the failure of exchange rates to reflect purchasing-power parities. Nevertheless, using the Big Mac index in this way does give a useful preliminary snap shot of differences in what minimum wages can buy in different countries.
