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.
this narrative is a flawed one that in reality doesn't benefit the poor at all because the tax that is paid to the government either from gambling platform or any other sources ends up in mostly cases tot be squandered and embezzled by the same rich folks and even if part of it is being used to create amenities in the society, such amenities is going to end up being consumed by everyone in that society which includes both the rich population and the poor ones.
the only sure way the poor benefit from gambling is when he wins in a bet. take that out and there is nothing left for the poor gambling. the casino is always at an advantage because they are mostly on the winning side. the rich gambler doesn't have much to loose as long as he is not a reckless gambler but the poor gambler that most times gambles more frequently because of the mentality of most of them which thinks that they want to become rich through gambling, they are most shortchanged and looses the most even if it might not be as much as the rich.
