Pension funds pay a premium to the Pension Benefit Guarantee agency. In the event of a problem like this one, the funds come out of the premiums paid by participants, not from the taxpayers.
Who are the participants?
Did you watch King of Bain?
Yes, and just like the FDIC and Fanny and Freddie they have a permanent loss and run a massive deficit that is taken care of by Government back stopping. IE OUR MONEY!
It has long been a game of corporatist like Romney to use OUR MONEY to to feather their own beds. It is easy to make money if you are willing to do any number of unsavory and repugnant things. Ask any drug dealer how profitable it is. The difference being that Bain and Romney simply used existing Bankruptcy and lending laws to over extend companies and bankrupt them after looting all the assets.
Romney is not now and never has been a capitalist. He is a Crony Capitalist and Corporatist.
