First off, I like your writing style, this was fun to read.

I don't totally agree with your conclusion that economic depressions aren't fertile grounds for revolution. The 1905 Russian Revolution, which is said to have set to stage for the 1917 revolutions, apparently happened partially due to poor economic conditions:

Because the Russian economy was tied to European finances, the contraction of Western money markets in 1899–1900 plunged Russian industry into a deep and prolonged crisis; it outlasted the dip in European industrial production. This setback aggravated social unrest during the five years preceding the revolution of 1905.
