Wealth taxes are blatant "slopulism"

History demonstrates that wealth taxes are ineffective

So why do we continue to discuss them?

During the silly season, when Parliament was in recess and there was nothing better for political hackers to talk about, Gary Stevenson, a former City trader turned socialist firebrand known for his support of a wealth tax and "for dressing like a 16-year-old scally despite being a 39-year-old man" as Christopher Snowdon puts it in The Critic, briefly made headlines.

Perhaps Stevenson's most remarkable accomplishment was creating and presenting a Channel 4 documentary about himself and his beliefs, in which he allowed experts to humiliatingly and severely refute his arguments. His brief stint in the spotlight came to an end when he abruptly stopped using social media due to exhaustion and burnout.

Wealth taxes' main problem.

Unfortunately, there is still some life left in his ideas, and the new prime minister, Andy Burnham, is looking for additional funding to cover his spending obligations for a straightforward reason."defining fiscal question" of the present is where the money will come from, according to Gerard Lyons in The Times. For good reason, the majority of economists reject wealth taxes as a solution to that issue. However, when faced with more urgent issues, like enormous budget deficits to close and political constituencies to appease, politicians are likely to overlook sound economics.

As Chancellor John Healey prepares his first budget for delivery at the end of October, he has made it clear that he will not rule out tax increases. He also faces the challenge of funding new spending commitments from a prime minister whose premiership thus far seems to be distinguished primarily by his inability to see a spending commitment he doesn't like while rebuilding a fiscal buffer eroded by the Iran war and weak growth.

There are few options for Healey. It is unlikely that the Office for Budget Responsibility will increase its projections for future tax revenues or economic growth, and borrowing more money will be difficult. This fiscal year, gilt issuance has already reached about 250 billion, and debt servicing expenses are rising. Additionally, Labour's manifesto pledges prohibit raising any of the primary taxes. Thus, wealth and other taxes have long been the focus of attention, as they are offered as an easy solution to the problem.

As Lyons states, "They are not." Governments require "large, reliable and predictable" sources of revenue, which is why modern tax systems have developed as they have. Because of this, recurring flows of income, profits, and spending are typically the main sources of revenue. Approximately four-fifths of tax revenues in the developed countries that make up the OECD are generated by these taxes. This idea is broken by wealth taxes, which aim to collect revenue from a stock of wealth held in assets rather than from flows, which is much easier said than done. Those nations that have attempted to enforce them have typically given up. Where they still exist, they are merely an additional burden "on entrepreneurs, business owners and productive capital" rather than on idle wealth.

The Wealth Tax Commission, a group of independent experts tasked with examining the viability and impact of a wealth tax, is frequently cited by proponents of a wealth tax, but Lyons claims that the commission's own research refutes the argument. The Commission calculated that behavioral responses could reduce the tax base by seven to seventeen percent, even at a tax rate of only one percent. "Many people have plenty of assets but little money. When a tax is separated from regular cash flow, it eventually necessitates borrowing money or selling assets to cover the tax. It increases administrative complexity, changes behavior, and lowers asset values."

What makes wealth taxes so well-liked?

According to Snowdon, it is simple to paint opponents of wealth taxes as "bootlickers for the haves and the have-yachts," but "the reason most economists are dismissive of the idea is the same reason governments of both right and left have abandoned them over the years: they are costly to administer, don't raise much money and drive talent out of the country." The majority of those who support soaking the rich are unaware that the wealthiest people's money is "not just sitting there in a bank account." It is invested in shares, the value of which can rise or fall sharply on a daily basis. It is invested in assets and property whose worth is unknown until they are sold. Additionally, it is the worth of the companies they founded and own, the price of which is also unknown until they are put up for sale, for those who technically own £10 million or more.

According to Snowdon, determining an individual's wealth is the first step for a government looking to impose a wealth tax. However, this is an unavoidably costly and bureaucratic process that necessitates numerous arbitrary decisions that the individuals being assessed are free to contest. And the issues don't end there. There were wealth taxes in 12 OECD nations in 1990. There are only three now. They are used as alternatives to inheritance and capital gains taxes in Norway and Switzerland, while Spain's is "so full of holes that what remains can be considered largely symbolic" and generates so little revenue that most fiscal accounts do not even bother to list it. To put it briefly, governments that attempt to impose wealth taxes quickly realize that they are just not worth the trouble.

According to academic philosopher Joseph Heath, who writes on Substack, "more sensible proposals take five minutes to explain and therefore have little chance of being adopted in the current political environment" is the main reason we are still discussing them. Wealth taxes are a prime example of "slopulism" and "policy ideas that make for quick, effective soundbites," but they are ineffective and "almost universally rejected by experts." For those on the left, the main advantage of the concept is that it is very simple to explain: "Billionaires are bad, so let's take away their money!".

To see this, we don't even need to adopt a stance on whether inequality is a significant issue that needs to be addressed. Maybe you believe it to be. Even so, there is nothing that a wealth tax can do to achieve your goals that isn't already possible with the current tax systemthat is, by taxing capital income. Some may argue that this does not account for the increase in the stock of wealth when those assets increase in value or earn a return, but this is merely a justification for treating the increase as income and taxing it as it already occurs. All wealth-derived income, including dividends, interest, and capital gains, needs to be reported as income. As previously mentioned, the idea is still to tax the flow rather than the stock of wealth. "A wealth tax is the quickest and most natural way for people who are upset about the Elon Musks and Peter Thiels of the world to vent their frustration. Regretfully, tax policy should not be based on the desire to punish one's adversaries."

Speaking at Tesla is Elon Musk.

Heath was discussing the circumstances in the United States, but the situation in the United Kingdom is hardly any different. What can we anticipate from the current government in terms of tax policy, considering that regrettable fact? Not much. According to Kristian Niemietz on Substack, picture yourself as a politician who opposes wealth taxes but still wants to win over supporters. You have economic advisors who tell you that wealth taxes are ineffective, and you are aware that they are typically more trouble than they are worth. However, you also feel that the Gary Stevensons of this world have won the debate, and you need money as soon as possible. According to Niemietz, you would likely devise "all sorts of policies that mimic aspects of what a wealth tax is supposed to do, without being a wealth tax proper" in response.

That would explain many of the current government's otherwise perplexing actions, such as raising capital gains tax rates while lowering tax-free allowances, raising stamp duty land tax rates and rental income rates for landlords, and imposing a "mansion tax"a council-tax surcharge on properties valued at more than £2 million. The public is in favor of these reforms, according to polls. When the consequences hit home, they might not be as well-liked.

As Niemietz notes, all such adjustments are likely to reduce savings, investment, and wealth creation while generating very little additional revenue. However, there will be more direct, noticeable, and invasive repercussions. For instance, the government intends to dispatch tax inspectors across the nation to appraise residences thought to fall within the mansion tax's price range. In order to perform a valuation, those inspectors will be able to request access to people's homes. This may appear to be an invasion of privacy and a violation of civil liberties, but it is an unavoidable result of the bureaucratic process of valuing unsold wealth in order to levy wealth taxes. "If you think this is a very inefficient way to raise money, consider what an actual wealth tax would be like, which would have the same effect on all assets."

The lessons learned from the past must be applied by policymakers.

According to Viggo Terling in The Critic, the public's support for wealth taxes and higher rates may not be as strong as it first appears. The government has "convinced itself that the public is desperate to tax the rich harder." However, recent research from the Adam Smith Institute indicates otherwise. It is true that 61% of voters say they favor a wealth tax. However, support falls to 37% when it is further explained that a tax of this kind might push wealthy people overseas and decrease the funds available for public services.

Voters ought to be able to perform their own calculations. 60% of all income tax revenue is contributed by the top 10%. According to Terling, if enough net contributors leave Britain in order to avoid an ever-growing tax burden, the bill will fall on everyone else, either in the form of higher taxes or worse public services. It's concerning that the millionaire exodus appears to have started already. There are currently 442,000 sterling millionaires in Britain, the lowest number since the financial crisis and a 7% decrease since 2024. Britain's tax burden is already testing post-war highs a level the Office for Budget Responsibility has called "uncharted territory" and imposing new wealth taxes and leaving tax thresholds unchanged will change incentives dangerously for the super-rich and workers alike.

Currently, you may be subject to an effective marginal income-tax rate of 60% if your income falls between £100,000 and £125,140. However, 81% of people concur that people ought to be able to retain a larger portion of their income and pass it on to their offspring. "No major party currently bases its policy on that, and it is about as close as Britain gets to a definitive moral stance on taxes."

Politicians should stop "wasting public resources reviving failed ideas, especially ones that are more about political signaling than devising meaningful solutions" after learning from the past, according to Cristina Enache of Project Syndicate. Instead of tearing down the top in order to rebuild public trust in our political and economic system, we should concentrate on promoting growth and increasing opportunities."
