Stanley Druckenmiller, the man who broke the Bank of England and made $1 billion in 1992 by selling the British pound with his colleague George Soros, is worried about today's economy. For Druckenmiller, it feels like 2004, just before the financial crisis, just before the global economy slid into recession. "There is nothing more deflationary than creating a phony asset bubble, having a bunch of investors plow into it and then having it pop," the investor told the Lost Tree Club in Florida on Jan. 18.
