It's true that a number of European countries that previously had wealth taxes no longer do. However, European countries only collect taxes on residents. If you wanted to avoid wealth taxes you could simply move to another country (and the bar to doing so is very low in the EU...), whereas the IRS collects taxes on US citizens regardless of where they live. So the situations are not totally analogous and it's not clear that a wealth tax in the United States would also fail.

First, this is not true. I live in a country in Europe and I paid a wealth tax today, in fact.

Second, please re-read my comment above as to why you might have understood that.

America which claims global tax jurisdiction may have slightly different results.

And yet that haven for the rich, Switzerland, has a wealth tax. Explain please?

That's interesting, can you expand?
