The Clinton administration ramped up pressure on the banks to do sub prime loans. There was an article in the NY times in 1999 about it. As much as I didn't like John Mc Cain, he was warning about the mortgage mess for a year or 2 before it broke. It took a number of years for Clintons easy money make bad loans for more than the house was worth policy to cause the crash. Most blame the banks, but it was the federal gov't under Clinton that did it. Now to be honest, Bill Clinton did not start the sub prime mess, that actually dates back to Jimmy Carter. he simply doubled down on it.
I think the Gov't over reacted even at that, with bank bail outs, car bail outs, it was gov't elitist taking care of their rich buddies, Then came the federal union stimulus package that did nothing except funnel money to the public unions, to be kicked back to Democratic politicians. gov't elitist taking care of themselves.
The so called Bush crash was nothing compared to the Carter crash. And yes I went through both. At no time, did we have double digit unemployment, double digit inflation, with double digit interest rates, Home mortgage interest rates were in the high teens, gas shortages and rationing, an entire Banking industry (savings n loans) collapse, under Bush, Obama or Trump, We did under Jimmy Carter. My house had a 10.95 rate and that was only because of a Florida loan program.
