With a gambling addiction, is it different for poor people than it is for the rich?

My friend and I were helping his friend move because she was leaving her husband due to his gambling addiction. They are not people of means, or great wealth by any means. It made me think of the Twilight Zone episode ”Fever” where this man who hated gambling won a trip to the casino and someone gave his wife a dollar to use in the slots. He said he didn’t want to go home with evil gambling money and plopped it into a machine, it paid off a small jackpot. He eventually put that back in the machine and kept getting small “bumps”, but then it stopped paying but he felt he had to keep going because he was just one pull away from getting all his money back.

That made me think of Casino Royal, the James Bond flick and the characters in it that loved gambling but they were all wealthy and gambled over high-stakes poker.

I wondered if the motivation for gambling for the rich were different or the same as the poor. Logically to me the poor play for the hope of leaving with more money, money they probably need or can use, than they came with. The rich, to me, would seem to play for excitement, thrills, bragging rights, etc. If you can afford to play poker or sit at a blackjack table with a $5,000 minimum, they can afford to lose so trying to double their money is not the motivation.

How do you see it, are the motivations for gambling different or the same generally for the poor as it is for the rich?
