Not a few rich people, they want the happiness for the population in large. Stable currency so bankers can not rip off citizens from deflation and inflation.
If you only cares personal wealth, so be it. I can almost sure to say, the currency collapse is nothing new. Riots, protests, stock market close, and bank run...
Even you want to exchange gold to stocks, market can be closed for a long period of time. By the way, do you know it happen all the time? And do you know that once your stock deposited in the brokarege house, it does not belong to you just like your cash in the bank belongs to the bank that they only give you promise to pay back?
If you care to study what happens in currency collapse, look no further than Argentina, Mexico, Zimbabewe, Germany etc.
We have tendency to believe this will not happen to America, If you look at why gold rise, it just point to that way.
Gold is the Canary bird in the coal mine. (if you care to understand what that mean.)
