According to Soros, there's about to be an all-out class war.

Soros, who is 81, previously bet against the British pound in the early 90s and made $1 billion off its collapse. In the years since, he's remained active in investing, but also in advocacy. He's helped keep Wikipedia afloat thanks to impressive contributions and through donations to the Tides Center, has indirectly funded Adbusters, the Canadian anti-capitalist magazine that put Occupy Wall Street on the map. Speaking to Newsweek recently, Soros neglected to acknowledge his past successes, but instead offered a word of warning: a period of "evil" is coming to the western world.

"I am not here to cheer you up. The situation is about as serious and difficult as I've experienced in my career," Soros tells Newsweek. "We are facing an extremely difficult time, comparable in many ways to the 1930s, the Great Depression. We are facing now a general retrenchment in the developed world, which threatens to put us in a decade of more stagnation, or worse. The best-case scenario is a deflationary environment. The worst-case scenario is a collapse of the financial system."
