ACTUAL banks, the kind that take deposits and are regulated by the FDIC, have always been under strict capital adequacy rules and regulations, and can be taken over by the FDIC if they let their capital ratios fall below a certain threshold (this is the regime that the big investment banks have been put under by becoming bank holding companies or being bought by them).
It irks me when people so self-righteously blame "deregulation" for the crisis when they so obviously don't have a shred of knowledge about what they are talking about.
Citation please. And excuse me, but I do believe that even knowing about the 15:1 to 40:1 change, does qualify as a shred of knowledge.
It's not my responsibility to chase down the sources of other people's irrelevant points.
3 of the 5 companies that were allowed to do this have now sunk, the proof is in the pudding.
