I wouldn't stress about it. Where the heck else are they going to invest that kind of money and get any sort of decent return? At worst, they'll yank their money from direct investments in the U.S., and then quietly reinvest it via offshore shell companies and hedge funds, and via Asian and European multinational companies who will in turn invest in the U.S. Their idiot sheeple will be impressed, and the spoiled brat princes will continue to rake in huge returns to fund their decadent globe-trotting playboy lifestyles.
Where the heck else are they going to invest that kind of money and get any sort of decent return? Zurich, Geneva, Frankfurt, Luxembourg, Amsterdam, Milan, London, Hong Kong, Singapore, Tokyo, Shanghai, Seoul, Moscow?
