Why do they allow gambling to such extent when they already know how expensive it can be to the society? Why to allow casinos at the first place? It is because governments collect hefty taxes from this industry in order to let it run, the same goes to drugs and alcohol. If we expect the change, we need to be the change and start taking the first step so to let addicted gamblers come back under the category of normal gamblers who know and understand their limits.
What exactly do you mean by "to let addicted gamblers come back under the category of normal gamblers"? Do you want addicted players to come back to the tables? In my opinion this would be a very bad idea, because this would make these poor people worse off if they are able to gamble again.
