AIG isn't a company run by widows and orphans. The department that issued that insurance was full of the most stereotypical Wall Street shark assholes around, who thought they were smarter than everyone else and getting a big free payday. They got scammed in the way a casino scams the idiot wearing sunglasses at the craps table.

Yes, the government bailout of AIG went towards paying off their counterparties. But those were actual debts that AIG owed because of their own stupidity and greed. Had AIG gone bankrupt instead, the counterparties would not have received anywhere near full payment, and there's a compelling case to be made that that's how it should have been. But this idea that AIG somehow got screwed by having to pay off their shitty bets with our money is laughable and disgusting. If the shareholders want to sue someone, it should be their own board.
