there are some of the banks that didnt burn their fingers, they actually stronger off and this is negatively effecting them, e.g. JPMC which i really like... I guess in general if implemented properly it might be good, but it must be gradual and not all in one go otherwise it will hamper the profits of the banks now and that will negatively effect the economy and maybe put Citi in a even worse situation... to reduce risk they not allowed to lend to risky home owners (now much more of them exist and people arnt spending, so its much more difficult to make money with conventional banking - luckily for investment banking which the firm is pretty good at, hopefully this will be allowed to be associated to conventional banking still...) The banks that operate properly actually use things like credit default swaps to reduce risk by speading it to others (third party), thats the main reason why JPMC invented then in the first place, so the guys buying them speculated (their own stupidity) but the issuer actually used it to reduce risk. lol..
