Summary 


Why has inequality grown, and how can we make sure that the rich make their contribution to society?


 Why has inequality grown?

  • Let's start with data on UK wealth from the Office for National Statistics:
    • The bottom 10% (about 5.4 million adults) had an average wealth of £12,835 in 2022.
    • The top 10% had £2.35 million on average.
    • The top 1% held over £5 million each on average.
  • In total, 58% of UK wealth is owned by the top 20%, and 37% by the top 10%.
  • This shows starkly that we have massive wealth inequality in the UK.
  • What does that mean in real terms?
    • The bottom 10% only have some personal property — no financial security at all.
    • The top 10% have over £300,000 in the bank, enough to absorb almost any shock.
    • This is the difference between having wealth and being permanently vulnerable.

How did we get here?

  • Historically, wealth was accumulated by:
    • Enclosing land, claiming it and charging rent.
    • Colonising other nations, enslaving people and extracting their resources.
    • Exploiting mineral resources without paying for environmental damage.
  • Today, extraction continues through:
    • Monopolies — water, trains, energy, mobile phones — all protected by the state.
    • Banks and tech companies, which dominate markets and extract profit daily.
  • Meanwhile, the system is rigged in favour of wealth:
    • In my 2024 Taxing Wealth Report, I showed average tax rates by income group.
    • The richest pay lower average tax rates on total economic gains (earnings plus wealth increases) than the poorest.
    • On new wealth gains from 2011-2019, the richest pay about 4% tax on average.
    • This creates a rank tax system that promotes inequality.
  • In fact, every taxpayer in the top 10% receives an effective subsidy:
    • Through tax relief on pensions, they get nearly £9,000 a year on average, more than maximum Universal Credit or PIP payments.

So, how do we make sure the rich pay?

  • Not through a wealth tax, at least not yet. After 42 years in tax, I know:
    • Wealth taxes are easily avoided, hugely costly to administer, need immense political capital, and would likely raise only around £10 billion a year.
  • We can raise far more, more easily, by fixing the existing system:
    • Ending pension tax subsidies for higher-rate taxpayers in the top two income deciles could raise £14 billion.
    • Charging the equivalent of National Insurance on investment income over £5,000 a year could raise £18 billion.
    • Applying VAT to banking services (mostly used by the wealthy) could raise £8 billion.
  • The real key is to close all the loopholes, anomalies, allowances and low tax rates that currently let the wealthy dodge tax.
  • Only when that is done should we even consider a wealth tax — and we are nowhere near that yet.

In summary

  • Inequality has grown because wealth is heavily concentrated and protected by systems of extraction, monopolies, and tax privileges.
  • The wealthy pay less tax on their rising wealth than ordinary people pay on their earnings.
  • We can make them pay more by reforming existing taxes:
    • Scrapping pension tax subsidies for the rich, taxing investment income like work, and making banks pay VAT.
  • That's a fairer, simpler way to make the rich contribute, without the pitfalls of a premature wealth tax.

I look forward to your questions.
