I'm not sure what you want with more specificity. You're familiar with the situation, right? You want a book report on what happened?
Yes, the government exists, and no, a few extra loans for black people didn't crash the housing market. This was a problem between ratings agencies, salespeople, and financial instrument inventors.
That's fine and all but turning around and accusing the conventional wisdom of 'lacking a deep understanding' is a bit much.
However, the fact that a narrative with political implications is "mainstream" does nothing for its credibility. I try to understand how these things work and while it's a pretty nebulous domain, the factors I presented are what seem to be the most significant I've seen in explaining the behavior of the real estate market, and further, the market at large, in '01-'08.
We are both rightfully upset that the crisis "somehow led to trillions of dollars missing" -- while paper wealth and market cycles are inevitable, the magnitude and 'unfairness' of this event is clearly a problem. However, when you then confidently assert the cause: "banks got really creative, a bunch of people made nice bonuses, then when their fancy leveraged mechanisms went bad, we all had to bail them out" without any details or refutation of the explanation I posted, to which you were responding...
Well, what I read was "I'm not sure what happened but I don't like it [rightfully so], and this narrative gives me an easy scapegoat -- an evil, shadowy figure, of sorts -- to blame, which seems to absolve me of needing to understand any of the mechanics involved, and which also happens to validate my pre-existing political beliefs."
When we have a market crash caused by private actors trading and someone says "OBVIOUSLY the problem is GOVERNMENT" I think they're arguing backwards from ideology rather than working forwards from observation.
You will have to be a little more specific to discredit the economic mal-incentives created by the government and to spin that simple narrative.
And the amount of paper wealth lost in '07-08 was actually about 10 trillion, not "hundreds of trillions."
