Someone didn't learn about the de facto monopoly the SEC (federal gov't) gave the Big Three (Moody's, S&P, Fitch) at the time of the meltdown through its NRSRO status: https://en.wikipedia.org/wiki/Nationally_recognized_statisti...
The whole banking and financial system at that level has its tendrils wrapped so firmly around the gov't (and vice versa) that a failure there is hardly an indictment of free market principles.
