Don't you find a contradiction in your words? Is it really profitable for the government to take care that its citizens do not become addicted to gambling? No, it is not so. If a person stops playing, then taxes will not be collected from him, and the casinos themselves will not receive income and the state will not receive anything for the treasury. So think about this fact. Yes, I understand that it looks very cynical, but this is the current reality and nothing can be done about it.
You can imagine what will happen if many citizens addicted to gambling? That will gives more problem to each families to take care on of their family's members who addicted to gambling. They can commits many bad things as someone who addicted will needs money to keeps playing gambling. If crime increase in that country, that will makes the government busy to solve it and they must search for the root of the problem. And when the government find the root is because gambling addiction, they must help their citizens because that can impact to many things. The government can get taxes from the other businesses and they will realize that they can not get the tax from the gambling business because that can makes their citizen in trouble. But we know that many officer governments in many countries can be bribed by the casino so the casino doesn't have to pay the tax.
One of the main responsibility of the government is to make a country livable and making it secure into its citizens on which it will really be that a huge problem if they would really be able to see gambling addiction related kind of crime on which this has been caused by too much addiction due to uncontrollable gambling businesses that resides or available on such country. Whereas, the government will neither be making out some decision whether they will really be that still allowing it or would be making out such step on banning it out because of the effects that it do brings up. If they would really be prioritizing about taxation and revenue that it does give on a certain country then they wont really be caring about addiction then there's nothing we can do about it. Actually addiction is something a problem which is really that personal and if it turned out to be severe then this is where potential problems would really be rising and thats why on the moment that it will happen into you then it will really be normal that you should really be doing on what the things that must be done.
You are really indeed having that common sense whether you are still doing the right stuff or not. It is really just there are individuals who are really that good on controlling things and able to avoid addictions.
