Yes he is serious. From the second link:
The CRA wasn't responsible for the subprime crisis. If one disagrees - please provide the evidence that supports such a view. For example, please provide the volume of subprime loans by type and year for the GSEs, and then provide the default rates. Then provide the same data for the non-GSEs, e.g, Bear Stearns, Merrill Lynch, Lehman Bros, Citibank, Goldman Sachs, AIG, . . . . .
The federal spending and the GSEs were part of the problem, but perhaps a bigger problem with the distressed corporate debt that exploded in the 2000s, and in conjunction with the CDOs, CLOs, and various derivatives undermined the financial markets.
Making risky subprime loans is actually in violation of the CRA.
The government didn't force, bribe or coerce anyone in making fraudulent (illegal) or risky loans. People freely chose (as in free market) to do so.
And at the moment, government spending and lack of revenue is a really big problem - and it's unsustainable.
