Amidst difficult economic conditions, many governments in Europe are brainstorming ways to raise more money. One approach that's being widely discussed is to impose higher taxes on the super-rich.
However, this is easier said than done. Experts believe that directly implemented wealth taxes often fail. Why? Because the wealthy are clever. They can easily move their assets to other companies, foundations, or even to countries with very low taxes (often called 'tax havens').
"Wealth taxes tend not to generate much revenue," said one expert.
Instead, economists propose other methods considered more effective. For example, governments could increase capital gains taxes or inheritance taxes. Some also suggest that people who move to a low-tax country be charged a special fee.
The International Monetary Fund (IMF) agrees. According to them, raising income tax on capital is far fairer and more efficient than a net wealth tax.
Although many countries like Switzerland, Spain, and Norway still have wealth taxes, research shows that the super-rich often pay no taxes at all.
"We need to ensure that billionaires pay taxes, at least as much as other segments of society. This is a matter of fairness," said Gabriel Zucman, an economist who proposed a 2% tax on the wealthiest 0.01% in France.
Additionally, the Organisation for Economic Co-operation and Development (OECD) highlights another loophole. They note that income from investments and dividends is often taxed at a lower rate than income from salaries. This is certainly unfair, as "high-income individuals get more favorable tax treatment," they wrote.
Inheritance tax is also mentioned as a better option than a wealth tax. The reason is that an inheritance tax doesn't discourage people from saving for their future. Unfortunately, many European countries still grant large exemptions, especially for inherited business assets.
According to the Tax Justice Network, this issue needs to be fixed immediately. "High inequality can harm economic growth and even reduce life expectancy," said their CEO, Alex Cobham. The bottom line is that making the rich pay their fair share of taxes is good for everyone, including themselves.
