Much of the "Roaring 20s" that preceded the giant market crash happened because of zero oversight or regulation and saw tons of fraud, and, yep, tons of reckless margin trading. This created huge systemic risk that all came to bear on Black Tuesday, which led to unemployment, homelessness and bankruptcies. This led to the Securities Act of 1933 and 1934.

Further, the Glass-Steagall act, also of 1933 separated investment banks and depository institutions. I'll let you take one guess why this was necessary. I'll also let you take one guess what happened after it was repealed (in 1999).

Also kicked off in 1933 was the FDIC.

All three of these are incredibly relevant to crypto and to this specific conversation.
