Someone needs to sue Freddie, Fanny and the FHA for the writing of all the fraudulent loans that brought down the US banking system. They knew these loans were fraudulent, toxic loans and sold them to the banks.
That would be suing themselves even if they are obviously the main culprits. Remember Greenspan telling everyone fantastic time to get a variable mortgage and buy a house? What could go wrong, it was wealth generation at low/no cost he said.
