It's an easy way for European citizenship
A lot of European states have a wealth tax as well as estate tax, which is not a good thing for an old dude worth $17B. Heck, it's not even a good deal for someone like me, if you run the numbers. Coincidentally, Eric Schmidt was a big supporter of Biden's plan to "tax the rich". The _other_ rich, that is, not himself, of course.
Um, I don't think they do (I am from UK living in Germany). "Spain, Norway, Switzerland, and Belgium"[1] have a wealth tax, Switzerland is not in EU. So 3 of 27 EU nations have wealth tax.
I would say Norway is an outlier too due to oil revenues and other quirks. The only large nation in that list is Spain.
