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.
True, taxes.
The government can impose not just 2x or 3x or 4x in taxes that they get from the usual business or company but they can impose as much as they can.
And the casinos won't have that much anything to say as long as they're continuous in operation, they'll only be following the orders of the government where they're found.
