I agree whole heartedly with you, my point is that if you were going out to dinner(which probably cost 10-25c) or to a 5c movie you carried lots of CHANGE which was used like we used dollars, quarters, dimes and nickels were used as singles, fives and tens.
And my inference to people carrying large sums of cash refers to people who had it and were in the process of purchasing a house, an automobile, a washer a piece of property a gravesite a herd of cattle a winchester rifle and a list that goes forever, were usually done in CASH or possibly a letter of credit.
As for your statement that I would have to born then to understand, true I was born in 1949, in an suburb of Los Angeles to a wonderful couple of middle class parents. I didn't miss many meals growing up because my folks sacrificed to see that I had what was needed. They came from Russia, having barely escaped with their lives and having suffered so much in their lives to them the Depression in the US was an improvement.
