Wealth Inequality in Britain Since 2010 Explained

Wealth Inequality Has Widened

Since 2010, Britain has seen the number of billionaires rise from around 50 to well over 150, while many working households have faced years of pressure on living standards. Critics argue this reflects an economy in which wealth has become increasingly concentrated at the very top, even as public services and household finances have come under strain.

Britain has become noticeably more unequal over the past 15 years.
The number of billionaires has roughly tripled.

The UK now has one of the highest levels of inequality in Western Europe, and the second-highest income inequality in the G7 after the United States.

The Growing Wealth Gap

One of the defining economic trends in Britain since 2010 has been the widening gap between those with substantial wealth and everyone else. While the economy has experienced periods of growth, that growth has not been shared evenly across society.

Numerous studies by organisations including the Office for National Statistics (ONS), the Institute for Fiscal Studies (IFS), the Resolution Foundation, the Joseph Rowntree Foundation, and international bodies such as the OECD have highlighted increasing wealth inequality. Although they differ in methodology and emphasis, they broadly point to the same long-term trend: wealth has become increasingly concentrated among a relatively small proportion of the population.

This is not simply a question of income. Income is what people earn; wealth is what they own. Wealth includes property, investments, pensions, businesses and financial assets. Those who already owned significant assets have generally benefited from rising house prices, strong stock market performance and the appreciation of other investments. Meanwhile, millions of working households possess little more than the value of their home—or have no property at all.

The consequences reach far beyond bank balances.

For younger generations, the traditional route into the middle class has become increasingly difficult. Home ownership has fallen among younger adults compared with previous generations. Larger deposits are required, rents consume a greater share of income, and many graduates begin working life with significant debt. Even skilled professionals increasingly find themselves unable to buy homes in many parts of the country without financial help from their families.

Public Services Under Increasing Pressure

At the same time, many public services have come under sustained pressure. Local authorities have reduced services, NHS waiting lists have grown, social care has struggled to meet demand, and many communities have seen libraries, youth centres and local amenities disappear. For many working families, it has felt as though they are paying more while receiving less.

This growing divide has fuelled concern that Britain is evolving into a more polarised society. Rather than a broad and confident middle class forming the backbone of the economy, critics argue that the country risks becoming one in which wealth and influence are increasingly concentrated among a relatively small affluent minority, while a much larger majority faces greater financial insecurity.

Is Britain Becoming a “10%–90% Society”?

Some commentators have described this as the emergence of a “10%–90% society“—not because exactly 10% of people hold all the wealth, but as a shorthand for a society in which the interests of a wealthy elite increasingly diverge from those of ordinary working families. The concern is that as wealth becomes more concentrated, so too does political influence, investment opportunity and access to the best education, housing and healthcare.

This trend matters because history suggests that societies with a strong middle class tend to enjoy greater economic resilience, social mobility and political stability. When large sections of the population feel they are no longer sharing in national prosperity, trust in institutions declines, political divisions deepen and support grows for more radical solutions on both the left and the right.

Can Britain Reverse the Trend?

The challenge for any government is therefore not simply to grow the economy but to ensure that prosperity is more widely shared. Supporters of Andy Burnham argue that stronger workers’ rights, investment in public services, affordable housing and fairer taxation are necessary if Britain is to rebuild a prosperous middle class rather than continue down a path of widening inequality.
