You know nothing about this… you truly are ignorant. Subprime lenders got hit hard, but the prime market that pushed the stated loans is what drove the market to collapse. The bad mortgages were packaged as A paper in investments tools and sold across the globe. Nearly destroyed the Icelandic economy. The prime market was the culprit and that is why Appraisal independence, QM/ATR and eventually TRID were added to TILA/Reg Z and Loss Mitigation servicing steps were added to RESPA/Reg X.
If it was only subprime, then the mortgage market wouldn’t have collapsed.
Get a clue…
