I was in argument with someone. His view is that people who gamble are those that what they have is not sufficient for them and so they try to make more money from gambling. He said if you have sufficient money to take care of your needs that you won't think of gambling. He made reference to some rich people, who don't gamble because they have sufficient money to even gift to charity but that those rich who still gamble are only addicted to it not just because of the money. Therefore, that the percentage of the rich gambling is very small compared to those in middle class and lower class.
The person you had the argument with is naive both about human behaviour and how the economy and businesses work. First the person need to understand that nobody gambles because they do not have enough. In fact it is to me the least reasons why people gamble. I have never seen a gambler who wins money from gambling and uses the money to start a business. They always return to gambling because they believe that more luck will shine on them.
What the person should argue is that the rich are more prudent and financially literate than the poor. Reason why the rich own the casino and the poor goes them to give them their money.
This is more logical indeed, I also think that people who do gambling are people who don't have money, to be precise they don't have enough money with them so they want to risk it in gambling to get more profit from practical profit methods even though they realize it's not easy to get profit from gambling because the percentage is very small, we need to take the average, and that's true.
Agree that someone who wins a decent amount of gambling won't even open a business, and usually they go back to gambling to double it again, if that's the reason it's definitely a fallacy.
Rich people think more about how they make money easily and don't make a loss, like the illustration you gave, the difference is that rich people make casinos while people who are below give their money, rich people have a more healthy and systematic mindset to earn money.
But personally, it's not that I don't have enough money or anything else as a reason for gambling, I'm just sometimes bored and gambling is a place where I get pleasure, and sometimes I want to try my luck. LOL
