In July 2026, Gary Stevenson told the 1.64 million subscribers to his Gary's Economics YouTube channel that he could no longer keep producing a video every week. He was exhausted, his health was suffering and he needed to stop.
It was an unusual moment for someone who had spent years telling viewers that Britain's economic problems were urgent and getting worse. Stevenson had gone from an obscure former City trader to one of the country's most recognisable campaigners on wealth inequality, helped by a simple argument: ordinary people are becoming poorer in assets while the very wealthy are accumulating more of them.
That claim has won him a large audience. It has also attracted plenty of criticism.
From Ilford to a City trading desk
Stevenson grew up in Ilford, east London, studied maths and economics at the London School of Economics and joined Citigroup as a trader. His career in finance later became the basis of his 2024 memoir, The Trading Game.
He says the defining trade of his career came after the financial crisis, when markets expected interest rates and economic growth to recover. Stevenson took the opposite view. His reasoning was that wealth was becoming concentrated at the top while ordinary households remained under pressure, making a strong recovery much less likely.
Stevenson has repeatedly described himself as Citigroup's most profitable trader globally in 2011. That description is disputed. A Financial Times investigation in 2026 found former colleagues who supported the narrower claim that he was the most profitable trader in developed-market G10 foreign exchange, but found no evidence that Citi maintained a ranking covering every trading division worldwide.
The distinction matters, but it does not change the more relevant part of his story: Stevenson made substantial money trading interest rates and currencies before leaving banking and eventually turning to economic campaigning.
The idea behind Gary's Economics
Stevenson's central argument is easier to understand than much of the economics discussed on television.
Imagine two households. One spends almost everything it earns on rent, food and bills. The other already owns several million pounds of property and investments, producing more income every year than it needs to spend.
The second household does not normally use that surplus income to buy thousands of extra dinners or pairs of shoes. It buys assets. Houses, shares, businesses and land become obvious destinations.
Stevenson argues that when this happens across an entire economy, wealthy households continually gain a larger share of the assets while people dependent mainly on wages find those assets harder to afford. House prices rise relative to earnings, rents absorb more income and younger workers struggle to accumulate wealth of their own.
This is the foundation of almost everything he talks about on Gary's Economics.
Why housing sits at the centre of his argument
Housing makes Stevenson's theory tangible.
If someone earning £35,000 is competing for a home with somebody who already owns several properties and has large investment income, they do not enter the market with equal financial power. Stevenson believes that concentrating wealth makes this imbalance worse over time.
The effect is then passed through generations. Someone whose parents own a valuable home may receive help with a deposit or inherit property. Someone whose parents rent starts from a completely different position even if both earn similar salaries.
Official figures show that Britain still has substantial economic inequality, although the picture is less dramatic than some of Stevenson's rhetoric suggests. The ONS reported median household disposable income of £39,200 in the financial year ending 2025, while the richest fifth averaged 5.6 times the disposable income of the poorest fifth. Income inequality itself had been fairly stable rather than rapidly deteriorating.
That distinction between income and wealth is important. Stevenson is primarily talking about what people own, rather than what they earn in a particular year.
His answer is a 2% wealth tax
Stevenson's proposed remedy is unusually specific. He supports an annual 2% tax on individual wealth above £10 million.
Someone worth £9 million would pay nothing under that proposal. Someone with £11 million would be taxed on the £1 million above the threshold.
Campaign group Tax Justice UK estimates that such a tax could affect roughly 0.03% to 0.04% of the population and raise around £24 billion a year, although the eventual amount would depend heavily on valuation rules, avoidance, migration and how the legislation was designed.
Stevenson also wants income from capital to be treated more like income from work and argues for closing inheritance tax loopholes. His broader slogan is "tax wealth, not work".
The £24 billion estimate should therefore be treated as a policy estimate rather than money that could simply be counted on in advance.
Where critics push back
The strongest criticism of Stevenson is not that wealth inequality does not matter. Few economists would argue that ownership, housing affordability or inheritance are irrelevant.
The disagreement is over how much explanatory power he gives them.
Housing costs, for example, are also shaped by planning restrictions, the number and location of homes being built, mortgage rates and population growth. Weak wage growth involves productivity, investment and labour market conditions as well as wealth distribution.
His preferred wealth tax has similar complications. Valuing private companies, overseas assets or unusual property every year can be difficult. Wealthy individuals can also change behaviour in response to taxation, reducing the amount ultimately collected.
Critics of his Channel 4 programme How to Get Filthy Rich made a related point: Stevenson presented a clear diagnosis and a simple solution, but some of the people challenging his argument were able to expose areas where the economic story was more complicated than his presentation suggested.
My view: the diagnosis is stronger than the cure
My view is that Stevenson is at his best when he forces people to look at the difference between income and accumulated wealth.
British political debate spends enormous amounts of time discussing whether somebody earning £50,000 or £80,000 should pay slightly more income tax, while far less attention is paid to the difference between somebody who earns a salary and somebody who already owns £20 million of assets.
That is a real distortion in the way economic inequality is often discussed.
I am less convinced that a single annual wealth tax can carry as much weight as Stevenson sometimes places on it. Housing supply still matters, productivity still matters and badly designed wealth taxes can produce avoidance or valuation problems; the counterargument is that those implementation difficulties are reasons to design the tax carefully rather than abandon the idea.
The most persuasive version of Stevenson's case is therefore broader than "introduce a wealth tax and fix Britain". It is that governments should pay much more attention to who owns the country's assets and how that ownership changes over time.
What happens after Gary's Economics?
Stevenson did not say in July 2026 that he was disappearing permanently. He talked about resting, travelling to Japan and possibly returning through occasional videos or a podcast rather than maintaining the exhausting weekly schedule.
His bigger test may have little to do with YouTube subscriber numbers anyway.
If house prices continue to separate from the incomes of younger workers and wealth keeps concentrating among people who already own substantial assets, his argument will become harder for mainstream economics and politics to ignore. If housing becomes more affordable and living standards improve without the kind of redistribution he proposes, that would weaken one of his central claims.
That is what makes Stevenson worth following. The interesting question is no longer whether an ex-City trader can build a large economics channel. He already did that.
The question is whether his explanation of Britain's economic problems survives contact with what happens to Britain next.
