I know about that 1936 rebound (that was followed by a mini-recession soon after, if I’m not mistaken) but I think a lot of wealth had “evaporated” in the preceding 6-7 years and a lot of former wealthy people had become bankrupt, it was not that easy to just “hold on” for a few more years.

Later edit: You can also make the case that the 1929 crash paved the way for an entire class of investors to be physically wiped out about 10 years later, I’m talking about how that economic crisis helped Hitler come to power and about the subsequent physical elimination of most of the European Jews. All I’m saying is that sometimes the apocalyptic estimations really do become true.
