As i understand from articles, the securitization of every subprime loan can earn bankers millions of dollars. So they give out as many loans as possible to scam the security buyers.
Nobody was getting scammed in this situation. Everyone knew exactly what they were getting. Security Buyers aren't stupid. They knew they were buying sub-prime loans. This kind of thing occurs when there is too much investment capital and not enough places to get healthy returns. Investors start taking bigger risks hoping to increase returns. They get what they bargained for.
