Indeed, in some countries, official gambling generates funds used for tuition, economic progress, and other government programs. Even so, the source of the funds remains an activity that clearly makes people greedy and selfish, and wants to be rich without effort.
Thats what you called as tax however even if government keep raising the tax of a gambling company, they will just keep on making money. It is not about being wrong about gambling but rather why would anyone want to gamble anymore if there is a very tiny chance to win? I dont think that is enough reason atleast for me
