Yeah, peace doesn't work too, every single European country that's tried it has reneged on it at least once in the past century, except maybe Switzerland and the Vatican.

More seriously though, issues like wealth taxation, capital gains taxation, inheritance taxes etc. are I would say more of a reflection of the relative strength of large property owners (a.k.a. "Capitalists" or "The 1%" to use other colloquial terms) versus the rest of the populace, to set economic-cultural norms and influence legislation.

Certainly, if such a tax is put in effect, many of the wealthy would make an effort to hide their assets away, possibly even abroad. But if the (federal) state wanted to cope with or overcome this potential tendency - which it really does not in the ultra-bought-off US political system, including Ms. Warren - there are many ways it could do so, both on the national and international levels. Not to mention how US corporations already employ asset and activity off-shoring to evade taxation.
