Hating Wall Street is an American tradition that dates back even to the days when Thomas Jefferson cursed that money lover Alexander Hamilton. And for centuries, the complaints about it have largely stayed the same: 'It does nothing! It creates chaos! It's a parasite that sucks hardworking Americans dry!'

Unlike physics, economists don't settle things. There seems to be plenty of room for different conclusions that are still accepted in the academy.
