Yeah, that's why the gambling businesses are standing firm and the effect they give positively to the government through their contribution and taxes is quite big. While on the other side, they also know that there's a bad effect on those addicted gamblers that can no longer control themselves. Well, there's a balance, there's good and bad but worse for the gambler that can no longer redeem himself because of his severe addiction and don't know where to get help.
