With more time, I'd come down on this like a million-pound sh*thammer. As it is, I'll just say a couple of things. First, you've done a very good job of reciting the history of the Great Depression you've been taught. But it's not true. Both the immediate and deep causes of the 1929 crash were far more rooted in the rising protectionism of the preceding decade and the screwed-up economics of the Treaty of Versailles. Only the very last step in the process was a function of "free markets" -- i.e. the runs on the banks once it was clear that the game was well and truly up. A secondary element of the specific issue of the stock market crash was margin buying, but that would have worked itself out if left alone.
If you want a far, far better analogy than 1929 to the current situation, the "Panic of 1873" is much closer:

Jumping from "credit crisis" to "unfettered capitalism is bad" is just as simplistic as the caricature of Palin, BTW as a knuckle-dragging moron. Satisfying, but essentially BS.
I was adressing two quite separate points advanced by Spacenut: 1. America should leave markets alone. 2. Poor people taking out loans they couldn't afford is the root cause of the current crisis. I separated those two points graphically

and I don't believe I mixed them together at all, except to conclude that economic stability, achieved through government administered "economic medicine," is good - for stocks, banks or other segments of the economy. I used the 1929 crash to illustrate point 1. becuse its the only crash everyone (including myself) can specifically recall.
Taking a very quick look at the Web, I find wide-spread American bank runs occuring in 1819, 1837, 1857, 1873, 1893, 1907 and 1929. (Am I missing any?) Wide-spread American bank runs since the New Deal: None. There must be a reason - 79 years without a wide-spread bank run significantly beats the averages. Even the S&L melt-down of 1989 didn't produce a panic, because of Federally mandated and backed deposit insurance, or so I have been taught.
I am no economist, nor even an amateur student of economic history, so yes, I am repeating the lessons I have been taught. Those lessons conform to the evidence I can see directly (no bank runs in my lifetime) so I accecpt them as true. I am certainly willing to learn new lessons, but I would also certainly regard any lesson that had to be administered with a sh*thammer as carrying no authority whatsoever.
