A little bit of background (copied from last year's thread on this subject, which was copied from 2020's thread):
Austria, Denmark, Finland, France, Germany, Iceland, Ireland, Italy, the Netherlands, Luxembourg, and Sweden all had wealth taxes and abolished them, leaving Norway, Spain, and Switzerland as the only countries that still have one.
France (which is the most heavily taxed country in Europe, a major reason being the retirement age of 62) keeps toying with the idea. Up to 2017 (when they mainly abolished it), 10,000 French citizens had left France taking 35 billion euros with them over the previous 15 years.
The rich find wealth taxes easy to avoid. If for example, farmland is exempt from a wealth tax, the rich purchase lots of exempt farmland, borrowing heavily to do so. The borrowing reduces the net worth of their other taxable assets.
Labour tried very hard to introduce a wealth tax in the 1970s. Denis Healey said "We had committed ourselves to a Wealth Tax; but in five years I found it impossible to draft one which would yield enough revenue to be worth the administrative cost and political hassle."
