What a whiny tone in the article... the man made money on people's downfall; why doesn't he repent? He must be punished!
Though short-sellers are hated, they are necessary. For every trader who goes short, there's a trader who goes long. No one is forcing them to enter this trade. They do so because they want to. Banning short-selling would be a disaster because prices would stop reflecting reality.
Paulson may have made money in an "unethical" way, but he played by the rules. I didn't hear any investment banks complaining about short-selling when they were making money. They were dumb. They lost. They won't be missed.
