Good points.
One relevant issue also would seem to be that the current mess is the result of a corrupt US Congress that's not representing the best interests of it's voters, but has instead been bought hook, line and sinker by the lobbyists of Wall Street who managed to sell with sufficient campaign donations a tall story of rewards having lost any correlation with risk, and of markets being fully able to take care of themselves, with de facto no regulations being necessary, which was the situation in the US before Wall Street imploded.
Now that arch protagonist of all-out cowboy capitalism is discussing nationalisation of banks on top of the 700 Billion US$ state bailout.
Of course bankers with more short term greed than long term reasoning, let alone reckoning, ability capitalised on that regulatory vacuum with the truly brilliant business idea of shoving credits down the throats of people who couldn't afford them, while afterwards trading around with these toxic timebombs.
Seeing the short half-life of such a business idea is not down to hindsight: it's simple common sense that such a snowball system carries the seeds of it's own destruction.
Short term greed resulting in a bubble just waiting to burst is not what I would call a Black Swan at all, it's simple, very predictable stupidity.
And this gigantic mess
a mere 20 years after the US had to rescue it's Savings and Loans banks in a pretty similar crisis driven by the exact same lack of regulation and ensuing short term greed coupled with mind boggling incompetence and total lack of risk awareness:
