Rich people are buying gold and Bitcoin to protect themselves if the dollar loses its power.
To some extend, sure, but they don't even have to given that the rich not only pay proportionally fewer taxes (and even fewer now, given the recent policy changes) but also often are first in line when receiving subsidies.
The biggest assurance the rich have got isn’t just how to escape some of these taxes or pay fewer taxes, they just know they are not below the radar and wouldn’t get crush if it does break or collapses. That’s why they don’t take much to fixing the broken system even though they know they can.
It gets even worse in developing nations where the arms of government might be independent but, bends to the will of politicians whom has made themselves a demigod over those they are to serve.
