To summarize, if you’re dumb enough to try to get rich in a Communist Country, be ready to deal with the fact that your country is, well, Communist. The implications are as follows:
1) If you criticize the government, you’re marked.
2) If you become popular you become a threat to the government, regardless of how much you may support them.
3) If you become rich enough, they’ll simply come and take what you have, should they have a budget deficit...or just want some spending money.
So typi8cally not such a great idea to try very hard in those countries.
If you become a billionaire, you'll just become marked by the government. That'll be stupid.
Solution, if you make more than enough money, get the hell out of there and take the money with you. If they limit the amount of money you can take out, use crypto currencies ( many Chinese are doing it ).
