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.

The engine of global productivity stuck in first gear

According to Christine Lagarde, Managing Director of the IMF, the slow growth in global productivity is acting as a brake on the growth in potential income and is thus holding back the growth in living standards. In a recent speech in Washington she said that:

Over the past decade, there have been sharp slowdowns in measured output per worker and total factor productivity – which can be seen as a measure of innovation. In advanced economies, for example, productivity growth has dropped to 0.3 per cent, down from a pre-crisis average of about 1 per cent. This trend has also affected many emerging and developing countries, including China.

We estimate that, if total factor productivity growth had followed its pre-crisis trend, overall GDP in advanced economies would be about 5 percent higher today. That would be the equivalent of adding another Japan – and more – to the global economy.

So why has productivity growth slowed to well below pre-crisis rates? One reason is an ageing working population, with older workers acquiring new skills less quickly. A second is the slowdown in world trade and, with it, the competitive pressure for firms to invest in the latest technologies.

A third is the continuing effect of the financial crisis, with many highly indebted firms forced to make deep cuts in investment and many others being cautious about innovating. The crisis has dampened risk taking – a key component of innovation.

What is clear, said Lagarde, is that more innovation is needed to restore productivity growth. But markets alone cannot achieve this, as the benefits of invention and innovation are, to some extent, public goods. They have considerable positive externalities.

She thus called on governments to give high priority to stimulating productivity growth and unleashing entrepreneurial energy. There are several things governments can do. These include market-orientated supply-side policies, such as removing unnecessary barriers to competition, driving forward international free trade and cutting red tape. They also include direct intervention through greater investment in education and training, infrastructure and public-sector R&D. They also include giving subsidies and/or tax relief for private-sector R&D.

Banks too have a role in chanelling finance away from low-productivity firms and towards ‘young and vibrant companies’.

It is important to recognise, she concluded, that innovation and structural change can lead to some people losing out, with job losses, low wages and social deprivation. Support should be given to such people through better education, retraining and employment incentives.

Job losses and labour mobility

Lloyds Banking Group has announced that it plans to reduce its labour force by 9000. Some of this reduction may be achieved by not replacing staff that leave, but some may have to be achieved through redundancies.

The reasons given for the reduction in jobs are technological change and changes in customer practice. More banking services are available online and customers are making more use of these services and less use of branch banking. Also, the increasingly widespread availability of cash machines (ATMs) means that fewer people withdraw cash from branches.

And it’s not just outside branches that technological change is impacting on bank jobs. Much of the work previously done by humans is now done by software programs.

One result is that many bank branches have closed. Lloyds says that the latest planned changes will see 150 fewer branches – 6.7% of its network of 2250.

What’s happening in banking is happening much more widely across modern economies. Online shopping is reducing the need for physical shops. Computers in offices are reducing the need, in many cases, for office staff. More sophisticated machines, often controlled by increasingly sophisticated computers, are replacing jobs in manufacturing.

So is this bad news for employees? It is if you are in one of those industries cutting employment. But new jobs are being created as the economy expands. So if you have a good set of skills and are willing to retrain and possibly move home, it might be relatively easy to find a new, albeit different, job.

As far as total unemployment is concerned, more rapid changes in technology create a rise in frictional and structural unemployment. This can be minimised, however, or even reduced, if there is greater labour mobility. This can be achieved by better training, education and the development of transferable skills in a more adaptive labour force, where people see changing jobs as a ‘normal’ part of a career.

Private versus public

Many people are attracted to work in the private sector, with expectations of greater opportunities for promotion, more variation in work and higher salaries. However, according to the Office for National Statistics, it may be that the oft-talked-of pay differential is actually in the opposite direction. Data from the ONS suggests that public sector workers are paid 14.5% more on average than those working in the private sector.

As is the case with the price of a good, the price of labour (that is, the wage rate) is determined by the forces of demand and supply. Many factors influence the wages that individuals are paid and traditional theory leads us to expect higher wages in sectors where there are many firms competing for labour. With the government acting as a monopsony employer, it has the power to force down wages below what we would expect to see in a perfectly competitive labour market. However, the ONS data suggests the opposite. What factors can explain this wage differential?

Jobs in the public sector, on average, require a higher degree of skills. There tend to be entry qualifications, such as possessing a university degree. While this is the case for many private-sector jobs as well, on average it is a greater requirement in the public sector. The skills required therefore help to push up the wages that public-sector workers can demand. Another explanation could be the size of public-sector employers, which allows them to offer higher wages. When the skills, location, job specifications etc. were taken into account, the 14.5% average hourly earnings differential declined to between just 2.2% and 3.1%, still in favour of public-sector workers. It then reversed to give private-sector workers the pay edge, once the size of the employer was taken out.

Further analysis of the data also showed that, while it may pay to be in the public sector when you’re starting out on your career, it pays to be in the private sector as you move up the career ladder. Workers in the bottom 5% of earners will do better in the public sector, while those in the top 5% of earners benefit from private-sector employment. The ONS said:

Looking at the top 5%, in the public sector earnings are greater than £31.49 per hour, while in the private sector, the top 5% earn more than £33.63 per hour… The top 1% of earners in the private sector, at more than £60.21 per hour, earns considerably more than the top 1% of earners in the public sector, at more than £49.65 per hour.

The data from the ONS thus suggest a reversal in the trend of average public-sector pay being higher than private sector pay, once all the relevant factors are taken into account.

This will naturally add to debates about living standards, which are likely to take on a stronger political slant as the next election approaches. It is obviously partly down to the public-sector pay freeze that we saw in 2010 and also to a reversal, at least in part, of the previous trend from 2008, where public-sector pay had been growing faster than private-sector pay. However, depending on the paper you read or the person you listen to, they will offer very different views as to who gets paid more. All you need to do in this case is look at the titles of the newspaper articles written by the Independent and The Telegraph! Whatever the explanation, these new data provide a wealth of information about relative prospects for pay for everyone.

How costly is unemployment?

Unemployment is a key macroeconomic objective for governments across the world. The unemployment rate for the UK now stands at 7.9% according to the ONS, which recorded 2.56 million people out of work. But why is unemployment of such importance? What are the costs?

The economy is already in a vulnerable state and with unemployment rising by 70,000 people between December and February 2013, the state of the economic recovery has been questioned. Indeed, following the news of the worsening unemployment data, the pound fell significantly against the dollar, suggesting a lack of confidence in the British economy.

Although the increase in the number of people out of work is concerning, perhaps of more concern should be the number of long-term unemployed. The ONS suggests that more than 900,000 have now been out of work for more than a year. Not only does this pose costs for the individual in terms of lost earnings and skills, but it also imposes costs on friends and family and the wider economy. (Click here for a PowerPoint of the first chart, which shows the percentage of unemployed people out for work longer than 12 months.)

The chief executive of the Prince’s Trust focused on the costs of youth unemployment in particular, saying:

Thousands of these young people are long-term unemployed, often facing further challenges such as poverty and homelessness. We must act now to support these young people into work and give them the chance of a better future.

(Click here for a PowerPoint of the second chart, which shows how much higher the unemployment rate is for young people aged 18 to 24 than it is for the working age population as a whole.)

Furthermore, with so many people unemployed, we are operating below full-employment and thus below our potential output. Furthermore, the longer people are out of work, the more likely it is that they will lose their skills and thus require re-training in the future or find that there are now fewer jobs available to them based on their lower skill level.

In addition to this there are monetary costs for the government through lower tax receipts, in terms of income tax, national insurance contributions and even VAT receipts. With more people unemployed, the numbers claiming various unemployment-related benefits will rise, thus imposing a further cost on the government and the taxpayer. Another cost to the government of this latest data is likely to be the expectations of the future course of the economy. Numerous factors affect business confidence and unemployment data is certainly one of them. The concern is that business confidence affects many other variables as well and until we receive more positive data, the economy recovery is likely to remain uncertain. The following articles consider this topic.
