Politicians talking about ending the "everything goes"???

I dont get this, but basically Obama said he would stop Wall Street from going wild and speculating like mad, I think it was with derivatives, and putting rules and regulations into force. I dont understand, what is it he was talking about, what is it they want to prevent happening and think they can solve? In what way will they limit people to trade?

It appears to be the same idiotic political rhetoric that we heard in the early days of the Internet going public. Politicians were promising the “mum & dad” voters that they would rid the world of the ‘evil’ internet so that their vulnerable children wouldn’t have access to free pornography. This was after they heard that a 10 year old downloaded a picture of a naked woman...you could see her boobies :-0

Most likely things measures such as increasing capital requirements for banks, to stop them leveraging 30:1.
