There are various currency controls that do make it hard to get money out of the country. Clearly it's possible, but if this starts happening in mass just watch as the top leadership makes that essentially impossible.
Sadly don't think it's stopped anyonw. Friend told me it's 50,000/person at any one time, but given the amount of money I've seen being being spent, I doubt that is stopping anyone.
Going to dig into if there are any loopholes for this. I think it's fascinating how so many people in China suddenly became self-made millionaires/billionaires + can spend that money so extravagantly in the US without much consequence.
There was a classmate from China last semester who came to class every day in a new custom sports car. Mondays was Lambourghinis, Tuesdays was R8, Wednesday was McLauren, Thursday was wrapped Panamera turbo, etc. And this kind of spending/demographic is pretty noticeable in Boston/Allston.
