The wealth creators are leaving Britain — and we could all pay the price The billionaire who gave Britain £330million — then leftHe also paid £330million in income tax — enough to fund the salaries of roughly 10,000 newly qualified nurses. And while renovating his vast 200-room stately home in Wiltshire, he reportedly spent another £175million with architects, builders, carpenters, plumbers and countless businesses in the supply chain. Then came the punchline. Rokos is moving to Athens. His firm, Rokos Capital Management, is opening an office in Greece, where wealthy foreign residents can benefit from a €100,000 flat tax on overseas income. Britain, meanwhile, is becoming an increasingly expensive place for wealthy people to live, invest and eventually pass their assets on to their children. Rokos is perfectly entitled to leave. The question is why Britain is making it increasingly attractive for people like him to do so. This isn't really about billionairesIt is tempting to dismiss the whole thing as a rich man's problem. It isn't. You don't have to feel sorry for billionaires to recognise that successful entrepreneurs and investors generate enormous economic activity around them. They invest. They employ people. They buy property. They fund businesses. They support charities and universities. They pay huge amounts of tax. And when they leave, Britain doesn't simply lose their bank balance. It can lose their future investment, future tax contributions, businesses, jobs and the economic activity generated around them. That is why the growing exodus of wealthy residents should concern everyone — including people who will never come remotely close to becoming millionaires. Britain is already losing its wealth creatorsRokos is far from alone. German-born investor Christian Angermayer has moved to Switzerland. Shipping billionaire John Fredriksen moved his operations to the United Arab Emirates. Pharmaceutical heiress Lady Ballyedmond is now living in Italy, while Yorkshire businessman Malcolm Healey has moved to the United States. Lakshmi Mittal, once Britain's richest man and a former Labour donor, has also announced his departure. The Sunday Times Rich List now contains fewer billionaires than it did several years ago, while a substantial proportion of those appearing among Britain's richest people are no longer resident here for tax purposes. That should set off alarm bells in Whitehall. And it isn't only billionairesThe much bigger warning comes from the millionaire class. Henley & Partners estimates that thousands of millionaires left Britain in 2025, taking tens of billions of dollars in wealth with them. The destinations are revealing. Portugal offers lifestyle. Italy has created an attractive tax regime for wealthy foreigners. Greece has aggressively courted international investors. And then there is Dubai, where wealthy expatriates face a dramatically different tax environment from Britain. Thailand has also become increasingly attractive to wealthy Britons seeking a combination of lifestyle and a more favourable tax regime. Once people discover that moving abroad is actually possible — and that they can maintain their businesses and investments while doing so — the psychological barrier begins to disappear. Labour has been warnedThis isn't some sudden Conservative invention. In February, Mark Goddard, UK chief executive of Swiss bank Lombard Odier, warned the then Chancellor Rachel Reeves that Britain's fiscal policies were making the country an increasingly difficult place to invest. He said he had hosted a dinner for eight entrepreneurs and six were considering leaving Britain. His warning was blunt: wealthy people don't simply take their money when they leave. They take their expertise, future tax contributions and willingness to mentor and finance the next generation of British companies. That is precisely the danger. Britain desperately needs investment and entrepreneurs who create businesses and jobs. Instead, the Government appears to be making the exit door increasingly attractive. The taxman has a problemBritain's tax system relies heavily on a relatively small proportion of high earners. The top 1 per cent of income taxpayers contribute a huge share of total income-tax receipts. And that creates a rather obvious vulnerability. The Treasury doesn't need millions of wealthy people to leave before the numbers become painful. It only needs enough of the very highest earners to decide that Britain is no longer worth the price. Rokos provides an extraordinary example. His reported £330million tax bill alone was almost half the amount paid in income tax by Britain's bottom three million earners combined. Now he is moving to Greece. The Treasury cannot simply wish that money back into existence. The danger is that everyone else gets the billThis is where the argument stops being about the rich. If high earners leave and tax receipts fall, the Government has only a few choices. Borrow more. Cut spending. Or raise taxes elsewhere. And Britain is already one of the world's highest-taxed major economies. The great irony is that a government which repeatedly talks about creating a "country of wealth creation" risks creating an environment in which wealth creators decide that their future lies somewhere else. That is not an argument for giving billionaires everything they want. It is an argument for understanding incentives. Once they leave, getting them back is much harderPerhaps the most worrying part is that this can become self-reinforcing. The first entrepreneur who moves abroad is taking a big leap. The hundredth is making a business decision. As more wealthy Britons establish lives in Athens, Dubai, Lisbon, Milan or Geneva, others discover that leaving Britain isn't nearly as frightening as they imagined. And once families have moved, businesses have relocated and children have settled into schools abroad, persuading them to return becomes considerably harder. A future government could promise lower capital-gains tax or a more attractive income-tax rate. But it cannot simply rewind years of lost confidence. Britain's real war on successThere is nothing inherently wrong with asking successful people to contribute their share. But there is a point at which taxation stops being simply about collecting revenue and starts changing behaviour. That is the danger Britain now faces. The wealthy are not an unlimited source of money. They are mobile. Their capital is mobile. Their businesses are mobile. Increasingly, their families are mobile too. And if Britain becomes the country where success is punished while countries such as Greece, Italy, Portugal and the UAE compete to welcome successful people, eventually the Treasury may discover the uncomfortable truth: You cannot tax people who have already left. And when the wealth creators go, the bill doesn't necessarily disappear. It may simply land on everyone who stayed. SOURCE
