And why wouldn't this happen again?

All the people and corporations whom profited dearly from the 2007 scam got off completely scot-free and were made then whole on the backs of the US taxpayers (actually, their grand or great-grandkids, because the money used to pay the bills was borrowed and added to the $20tril debt)

They fully expect to be bailed out again, so again I ask...with big money to be had and almost zero risk to the players, why would anyone think its not happening again?
