In scapegoating sub-prime lending the FSA is missing the point
I think that's only a partial truth.
There's nothing fundamentally wrong with sub-prime lending. The risks are much higher, but then so are the potential rewards. There should be companies that cater to that market.
The problem is that the sub-prime loans (very high risk) were bundled with a few lower risk bonds and then sold on as if the whole set were low risk. That was stupid and the FSA just let it happen.
