Here is why.
They learned by watching that they too can get bailouts by the taxpayers just like all the other mortgage lenders did who practiced the very same reckless practices. FANNIE, FREDDIE, and lots of other creditors.
THEN they all got creative and came up with toxic things called derivitives. These were all the under water mortgages because they all lent money to people without checking if they had a job, could they afford the loan, sub prime mortgages, 100 percent mortgages, etc.
EVERYONE got bailed out. Only the people who paid their mortgage payments as they should and their federal taxes got screwed.... Like we will again.......
