Is that how Soros made his billions? Follow the money.
Yes, he has been crashing economies with which to make money on the currencies in the process. The only one who beat him badly so far was Malathir in Malaysia when he instituted rules on minimum hold periods for currency trading. Soros admitted he lost over a billion on that one and that was back around 1990.
You'd have thought we might have learned something from it, but no, he gives money to Democrats. So when the market crashed in 2007 he made a bucket-load, IIRC playing gasoline futures.
