This is nonsense. Fannie Mae and Freddy Mac were socialized, even as they gobbled about huge amounts of bad mortage debt from other companies.
The only thing dysfunctional about capital markets is repeated FED interference in them. If these companies couldn't find money on the markets, then they should have gone bankrupt and been re-organized. Instead the FED bailed out their buds on Wall Street.
Indeed the FED did lend money to other companies and foreign central banks. The latter is virtually criminal in nature. They have zero authorization to do so. Nor did they have any authorization to steal money from taxpayers and GM creditors and turn it over the UAW.
I'm not sure why lending abroad is criminal. National borders aren't that important to the world of finance. The Euro collapsing would be felt around the world. Indeed the Chinese seem to be dumping money into Europe to stop that from happening.
