Yes, if you want to put it very pointedly, the Great Depression was caused by cutting taxes and paying off the national debt - by doing so at the expense of your trading partners.
The Depression was in full swing well before the Stock Market Crash - farm incomes were declining, in real terms, all through the 1920s, and America was still a very agrarian country in 1920.
In fact, I believe Stock Market Bubbles are a crisis symptom. People won't invest like mad in stocks they hardly know anything about if there are sounder investment options nearer at hand.
Stock market bubbles are a symptom of artificially inflating the money supply.

They're also a way to artificially inflate the money supply...the question then would be: In what circumstances is the money supply artificially inflated? And how had we previously defined "artificial" again?
Might it have something to do with "creating an imbalance"? (This one, unless the ones above, is not a rhetorical question, btw.)
If so, isn't that really the same as a crisis symptom, since it means markets won't function "properly"?
