US unemployment rocketed to more than 20% during same interval. Note that this was a time of single income families. As we all know, official unemployment rate under reports unemployment. Safe to say that more than a quarter of all workers were out of a job. Also, many workers that had jobs were kept them by accepting less pay. States and counties were practically bankrupt. Many state and county workers had a job but practically no income.
To repeat what you said, "if you had a job (with a good income), you were fine". I added a few words to make it correct. But for the most part across the country people were not "fine". The economic crash created deflation. Once the cycle of deflation set in, the economy kept spiraling down. It took massive government spending during the war era to break the hold that deflation had on the economy.
