Flaunting your money was tacky and in bad taste. It was taken for granted that anyone who drove a Cadillac and generally acted rich, was too slick, a gouger who made too much profit, a show boat who was putting up a front or possibly all 3 - in any case a person of no substance who was not to be trusted. No one would be so foolish as to do business with such a person.
A little tale of a Millionaire from my neiborhood. When I was a young lad raised in a lower middle class working neiborhood, Circa date 1964, there was an older fellow ( my granddads age) that everday would get in his old beat up station wagon and go around the town picking thru thrash and newspapers bottles etc, The ultimate junk man.. Turns out when this fellow passed, he willed over $1.2 million to the church and owned most of the ground that myself and all my friends played on everyday. It was also rumored that he had over $200k in cash scattered thruout his unkeeped, falling down house. Moral of the story, one never knows what another is worth. However I believe money was created to use for the finer things in life and should be enjoyed to a certain degree. One should not inspire to be the Richest person in the graveyard.
A good read is " The Millionaire Next Door"
Like a Millionaire once told me. Money isn't everything but it sure helps a Hell of a lot.
Didn't Jackie Gleason also say: "I have been rich and I have been poor. Rich is definitely better. "
