In general, I can understand your point of view, but there is one aspect. Doesn't the rich risk more than the poor? I mean, the poor will quickly stop playing, because he knows that there is no money. But the rich can play and play, feeling their huge deposit behind them. And so the situation can get out of control.
Yes, I agree with you, a rich gambler has more to lose than a poor gambler, but come to think of it, how many addicted rich gamblers do we see everyday? The population of poor addicted gamblers are way more higher than that of the rich, this is because most poor gamblers gamble to make money and probably to get financial assistance to sort a bill or solve a problem, and as we already know, this is the easiest pathway to gambling addiction and you rarely see the rich going down this path because majority of the rich gamblers only gamble for the fun and thrill of the game and this helps them to regulate their gambling habit and also their risk management which makes them to avoid overspending on gambling. But this isn't always the case for the poor gamblers as they're mostly after the financial benefits of gambling rather than fun aspect.
If we google for what people did with their jackpots, then we would find that many of them did not spend money smart. I remember a story of a garbage cleaner from UK who won a huge amount of money and waste them in 5 years, which made him to return to previous job. I believe if a person wins a jackpot, he totally isnt ready for that, he isnt a jackpot hunter. And when he gets the money, that person has a feeling of «not believing he is rich now», so he starts spending a lot or gambling. Those lucky who suddenly became rich from gambling have poor financial education.
However, if I become rich (I am not saying that I am financial guru), I would spend money on traveling and looking for new places and experience. Gambling for me would be a past experience, to which I think I wont return soon or ever.
