I wonder how many "obscenely" wealthy there actually are in the US because none of the much abused one-percenters that I know are what used to be called the "idle rich." Even if you start with 380k per year, taxes, school-age children, and aging parents cut that figure down pretty quickly.
Anyway, the fastest way to scare rich people out of your country is to tax them obscenely. Have you seen the Parisian real estate market lately? A glut of rich-people houses up for sale because all the have's are decamping to Luxembourg and Switzerland, they and their money. (And, naturally, the houses are being gobbled up by wealthy foreigners who pay no income tax.)
