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.

Is growing inequality fair?

In a series of five podcasts, broadcast on BBC Radio 4 in the first week of January 2021, Amol Rajan and guests examine different aspects of inequality and consider the concept of fairness.

As the notes to the programme state:

The pandemic brought renewed focus on how we value those who have kept shelves stacked, transport running and the old and sick cared for. So is now the time to bring about a fundamental shift in how our society and economy work?

The first podcast, linked below, examines the distribution of wealth in the UK and how it has changed over time. It looks at how rising property and share prices and a lightly taxed inheritance system have widened inequality of wealth.

It also examines rising inequality of incomes, a problem made worse by rising wealth inequality, the move to zero-hour contracts, gig working and short-term contracts, the lack of social mobility, austerity following the financial crisis of 2007–9 and the lockdowns and restrictions to contain the coronavirus pandemic, with layoffs, people put on furlough and more and more having to turn to food banks.

Is this rising inequality fair? Should fairness be considered entirely in monetary terms, or should it be considered more broadly in social terms? These are issues discussed by the guests. They also look at what policies can be pursued. If the pay of health and care workers, for example, don’t reflect their value to our society, what can be done to increase their pay? If wealth is very unequally distributed, should it be redistributed and how?

The questions below are based directly on the issues covered in the podcast in the order they are discussed.

The geographical immobility of labour in England – a social problem

Where you live in Great Britain can have a profound effect on your earning potential. According to a report published by the Social Mobility Commission, there is a growing geographical divide, with more affluent areas getting relatively richer, while ‘many other parts of the country are being left behind economically and hollowed out socially’.

The Commission uses a Social Mobility Index to rank the 324 local authorities in England. The index is a measure of the social mobility prospects for people from disadvantaged backgrounds. It is ‘made up of 16 key performance indicators spanning each major life stage’.

The index shows that children from disadvantaged backgrounds have lower educational attainment, poorer initial jobs and poorer prospects for advancement in the labour market. Often they are stuck in low paid jobs with little chance of getting on the housing ladder and fewer chances of moving away from the area.

The problem is not simply one of a North-South divide or one of inner cities versus the suburbs. Many inner-city areas have been regenerated, with high incomes and high social and geographical mobility. Other inner-city areas remain deprived.

The worst performing areas are remote rural or coastal areas and former industrial areas, where industries have closed. As the author of the report states in the Guardian article linked below:

These areas have fewer specialist teachers, fewer good schools, fewer good jobs and worse transport links. … Many of these areas have suffered from a lack of regeneration: few high-paying industries are located there, and they often exhibit relatively limited job opportunities and clusters of low pay.

The problem often exists within areas, with some streets exhibiting growing affluence, where the residents have high levels of social mobility, while other streets have poor housing and considerable levels of poverty and deprivation. Average incomes for such areas thus mask this type of growing divide within areas. Indeed, some of the richest areas have worse outcomes for disadvantaged children than generally poorer areas.

There are various regional and local multiplier effects that worsen the situation. Where people from disadvantaged backgrounds are successful, they tend to move away from the deprived areas to more affluent ones, thereby boosting the local economy in such areas and providing no stimulus to the deprived areas. And so the divide grows.

Policies, according to the report, need to focus public investment, and incentives for private investment, in deprived areas. They should not focus simply on whole regions. You can read the specific policy recommendations in the articles below.

Keeping it in the family

An article in the February 2015 issue of the Economic Journal, ‘Intergenerational Wealth Mobility in England, 1858–2012: Surnames and Social Mobility’ by Gregory Clark and Neil Cummins, looks at the persistence of wealth within British families across the generations. The article shows, ‘using rare surnames to track families, that wealth is much more persistent than standard one-generation estimates would suggest. There is still a significant correlation between the wealth of families five generations apart’.

It concludes that down the generations the main determinant of wealth is inheritance, despite all efforts to improve social mobility. The intergenerational elasticity of wealth inheritance is found to be 0.70–0.75 throughout the years 1858–2012. In other words, people’s wealth on average will be between 70% and 75% of that of their parents. Thus a large proportion of each person’s wealth depends on the wealth of their parents and a relatively small amount depends on other factors. As Clark and Cummins conclude:

The implications of this model are that wealth will be surprisingly persistent in families across multiple generations. This is what allows rich rare surnames to still remain rich on average even four generations later. It also implies that wealth differences between racial, religious and ethnic groups will also be highly persistent across generations.

So it is just inherited wealth in terms of money or property that gets passed from generation to generation? Or are their other factors, such as education, social class and social contacts, that cause people’s wealth to depend heavily on that of their parents? Clark and Cummins consider this question.

What is the latent variable that underlies the inheritance of wealth? Evidence in other work we have done on the inheritance of education status in England suggests that families can be conceived of as having an underlying social competence, which is highly persistent across generations. This social competence generates their outcomes on all dimensions of social status but with random components on each one. In this case, social mobility between generations measured on any single aspect of status will be much greater than mobility on a more general ranking of families’ overall social status, that averages earnings, wealth, occupation, education, health and longevity.

So does this mean that attempts to create greater social mobility and greater equality are futile? The authors maintain that although it is difficult to achieve greater social mobility, income and wealth can nevertheless be redistributed through the tax and benefits system.

BBC Radio 4: The future is not what it used to be

On my commute to work on the 6th May, I happened to listen to a programme on BBC radio 4, which provided some fascinating discussion on a variety of economic issues. Technological change is constant and unstoppable and the consequences of it are likely to be both good and bad.

In this programme some top economists, including Joseph Stiglitz offer their analysis of the impact of technology and how the future might look, by considering a range of factors, such as youth unemployment, the productivity of labour, education, pensions and inequality. The benefits of new technology can be seen as endless, but the impact on inequality and how the benefits of technology are being distributed is a concern for many people. The best introduction to the programme and its content is simply to reproduce the description provided by BBC radio 4.

The baby boom generation came of age when it was accepted knowledge that innovation and productivity would always lead to higher standards of living. The generations which followed assumed this truth would continue into the future indefinitely. With the crash of 2008 the upward mobility the middle classes assumed was their right evaporated, and it is unlikely to return.

Martin Wolf, chief economics commentator of the Financial Times, asks how the work force of the future will be changed by the advancements of technologies. How should governments respond to a jobs market which is hollowing out opportunities for traditional educated professions and how will rewards for innovation and income for labour be distributed without creating a society plagued by endemic inequality?

We will speak with optimists and pessimists on both sides of the argument to find out how the repercussions of these changes will affect the way we all live now and well into the future.

It is well worth listening to and provides some interesting insights as to what the future might look like, as the inevitable technological change continues. The link for the programme is below.
