Let me clarify. The primary debt issuance was debt taken by people doing stock market speculation. The joke at the time was that if your shoe shine boy was asking you about stocks, something weird is about to happen.
The agriultural overproduction was a result of the drop in market prices for goods, so the farmers ramped up production to make up for it, ignoring good farming practices, notably proper tilling and crop / land rotation which resulted in the deterioration of the top soil (dust bowl).
All of this happened in the Roaring 20s.
As far as before the 20s, you had WWI and the industry kings manipulating the markets. They were doing fine, but the people working under them weren't. This was the era of industrialization, child labor and The Jungle. It was wonderful if you were an industry titan, but bleak for most everyone else.
Anyway, my point being, the great prosperity we experienced after WWII was more of an anomaly that anything else. I believe it was sustainable through smart regulation and government investment among other things, but interests have been working hard to bring us back to where we were before.
