To put an end to gambling is meaningless because people will always gamble on money, regardless casinos are legal or not. If they prohibit it, then there will be underground casinos and that will cause more harm than good. If poverty is high in your country, don't expect that gambling will give it any good but it will really increase your employment rate. For example, in my country, there are many casinos and they hire a lot of people, including dealers, shufflers, software developers, project managers, designers, customer support and etc... They probably hire a total of up to 10K people. If they put an end to gambling, up to 10K people will become jobless and gambling restriction is not going to put an end to poverty.
And even if they're to shut down gambling it's not going to affect the general society, but only individuals in your country, anyways they'll still find other means of survival cause you can't tell me gambling is the only way people survive in your country, however I think it's the casino owners that would be more worried of losing their business but I doubt if that would be possible due to the task generated from casinos to the government except maybe a government discovers that lots of it's citizens use it for money laundry that's when they'll be forced to step in.
