NNNNNNOOOOOOOOOOO!!!!!!!!!!!!     The whole lesson of the US disaster is that when the government regulates the financial sector, and GUARANTEES that depositors will get paid, regardless of the idiotic loans made by said financial sector, depositors are not careful, and banks don't care about loan quality.  Why would they? They get paid on volume, they bundle crap loans into MBSs and sell them to UBS, or they keep the loans on their books, but cover their butts with fed-backed mortgage insurance.  
Just make it clear that unregulated means "not bailed out," and if investors then want to fund such firms to chase high returns, hey good luck to them!
Please google CountryWide, IndyMac, Washington Mutual, or 100 other dead lenders in the US...
