the great depression was a global economic crisis, and only increased because of the money spent on war, but also because of all the blockades placed on imports/exports. england, asia, usa, couldn't trade. no cotton, no silk, no wool, which is where nylon came into effect.
also i think as for weapons and tanks a lot of the metal used came from women's corsets, which was surprinsingly a lot of material.
but yeah, most of the events causing the us market crash are pretty similar to whats going on now, too much debt, corporation overgrowth and the rich getting richer, the poor getting poorer, but mostly, in effect, the entire world being at war, the consumption dropping, costs rising beyond belief, and money because so high in value it became essentially worthless. i think it also factored in job loss were that some women may have stayed at work in america, and due to downsizing, most people came back from the war without promise of work.
