No major politician in the US is a socialist. Paul Wellstone was the last one I can think of that might have had some left wing beliefs, and even he was quite conservative on many critical issues. I just laughed when they were trying to call Obama a "socialist" and a "communist". The accusation was utterly ludicrous for someone that in any European country would be a mid range conservative. And no I don't believe the two US parties are different. Red/Blue US Conservative/US Liberal, Republican/Democrat are as meaningful as Ford/Mercury. Underneath they are the same corrupt conservative right wing corporate profit uber allis machine. It's why I packed up and left the US 8 years ago. I'm just watching the rot from afar.
So as far as your concerned we haven't destroyed the world economy enough? How far left do you want to go? Maoism? Leninism? Marxism? Maybe Hugo Chavez left or Trotsky left? Screw all this lets go all out with Carlos Marighella guerrilla marxism. That should fix the problems.
I've never understood the want or need to control.
