That is a good point. As well, many in these groups simply do not comprehend deferred gratification. They do not plan for the future and live solely for today. Every group has some folks like that but some groups are mostly composed of such people.
I remember reading the words of a sports agent some years ago who represented a number of NFL football players who were making great gobs of money. One the players was accused of non-payment to the mother of one of his children, and was taken to court.
His agent said the player literally had no money left after making half a million dollars a year for a number of years. The agent said many people didn't understand the mindset of many pro athletes which was to spend everything they earned and save next to nothing.
