The only folks who ever say that do so as above, attributing that belief to others in an attempt to cover up their lack of an actual argument.
Govt is subject to exactly the same failings, with one important difference - it gets to tax and coerce folks and there's even less connection to results.
Even the most corrupt company would have problems keeping Barney Frank around, yet he's still a major player in govt, driving housing policy....
Such a firm connection to reality.
How about the reality that regulation caused a lot of the problems?
Start with Fannie Mae and Freddie Mac. Ask whether anyone would be willing to make NINJa loans without a govt guarantee. And, if someone made such loans, ask whether anyone would buy them.
US Govt policy pretty much guaranteed that the mortage industry would take a huge fall. Even now, it's trying to keep people in houses that they can't afford. And, the money is coming from folks who bought what they could afford or rented because they couldn't afford to buy.
You may be under that impression, but it's wrong. (It's being pushed by folks who like regulation.)
They were all regulated to the hilt. AIG especially.
