What do you recommend for people who want to increase their wealth but aren't rich yet? The people who have potential and a solid foundation but don't yet have the capital necessary to move around like that and find the most favorable place.
This is the real reason the ultra-wealthy aren't taxed. People think that they are obviously going to become rich any day now, and they won't want to pay high taxes when it inevitability happens. Some strange, shared delusion of the middle class.
The ultra-wealthy pay more tax per capita than any other group. This is the opposite of "aren't taxed"
Of course investments in the country where corrupt polititicans are proposing doubling capital gain tax is not going to work.
If some aspect of that sounded less appealing, then you are back to momentum trading and looking for opportunities that distort the market and reality and bet the farm when you make the trade at all. Try to have fun, usually it comes with dopamine.
If that is really your perspective, why live in the US?
