Ahhh, the good old days. Average income fell by 40% between 1929 and 1933. And most people didn't need to worry about saving for retirement since life expectancy was about 60 years. And, of course, antibiotics weren't generally available, so people had more kids because they didn't expect them all to survive. Yes, people learned to make do.
Of course, anyone who looks back fondly on the Great Depression either didn't live through it or is delusional.
