Governments and several organisations work to encourage responsible gaming. This involves establishing betting restrictions, offering support to those who think they have a gambling problem, and participating in self-exclusion programmes.
Not so many countries care about the negative effect that gambling is emitting in the lives of their country's citizens, what they most care about is to create a peaceful environment for the smooth running of those casinos operating on their soil in return for the high taxes (money) that are paid into their purse. If you are referring to nongovernmental organizations and civil liberty organizations rendering support in encouraging responsible gambling I can agree to an extent but for the government I don't think they fucking care anyway. The only restrictions I see from the government is 18+.
Op don't forget that those self-exclusion programmes aren't for free, in some cases you have to be granted a subsidy where you incur part fees to benefit from those programmes. So it's like a win-win from the government achieving from the gambling companies and also from those who fall into gambling addiction seeking for specialist/rehab support. Lol.
