Let's first talk about how the poor gives the money to the wealthy.... They allocate a huge part of their money (which isn't a lot in the first place) to gambling thinking that this would be the quick fix to their problems. This is how they give the money to the wealthy in this case the casino owners.
That’s right, the poor gamblers are always thinking of making money with the little they have; they will keep using the money they have to gamble with the hope of getting a huge return in just one game. They do look greedy to expect a huge return from their small deposits they use to wager on games; they are given to the casino owners because such games hardly come due to the number of odds and the nature of predictions. However, it is very possible to make a huge amount of money with just a small amount of money being deposited, but it is very rare to see such achievements. Most people that win in betting do use big money to gamble on less odds.
But the money can also go from the wealthy to the poor. If the tax from casinos gets collected by the government and is used effectively, it can help a lot of those in need. The money can be used to improve infrastructure, education, healthcare and etc.
Yes; the poor gamblers can benefit from the tax return from the casino, but they will benefit more if they are lucky to win games from their betting. Sometimes, these casino owners do also lose huge amount of money especially if some players are lucky to win games back to back with just small deposit.
