So if the rich don’t like paying their fair share if the taxes, they’ll just move? And go where? Any country they’d like is going to have even higher taxes than are being suggested in America. In addition, Americans living abroad still pay annual income taxes to America, as well as the country they live in.
They’d likely have to learn a new langugage, a new culture, new food, etc. They’d be far from the things they love about America, all so they can save money on taxes that wouldn’t improve their already opulent lives one tiny bit. Do you really think a multi-billionaire, who already is so wealthy that neither he nor his descendents could ever spend it all, is going to leave the incredible comfort of America just to save a few million in taxes that they’ll never even notice?
Rich Americans are still Americans, and most people are happiest where they grew up. Sure, its fun visiting other places, but you are always going to be happiest in the culture you are most familar with, provided there isn’t a dangerous economic or political situation.
Most would be loathe to give up their American comfort for another place. Nobody is really suggesting that American Oligarchs give up their comforts, just that they should keep a little bit less of their nearly limitless hoard of treasure to keep the system that benefits them above all others healthy, so they can get even richer.
We are an unapologetic Capitalist society, but the Sociopathic Oligarchs are killing the Golden Goose with their enthusiastic unbridled greed, and we are trying to save them from themselves. By taxing them only SLIGHTLY heavier, we are preserving that system so they can continue to get even richer. If they insist on continuing down the fraudulent Trickle Down path, the system will eventually break, and installing the new system will likely include a very bad situation for the wealthy.
But some people will leave. “American comfort” is not a thing. Switzerland, Monaco, Netherlands and some other countries are better places to live even for the working person(though there are not many of those in Monaco, to be fair). And trust me, if you are rich, it does not matter where you live, you will be perfectly comfortable wherever you are(but I would not prefer america anyway, though americans might feel differently).
