Big portion of profit of the casinos are coming from gamblers who just gamble for fun, and that would not affect the lifestyle of the gamblers as they are mostly responsible gambler, but it could help the economy to grow as government can restrict their people from gambling.
Casinos are obviously a good help to the economy of each country since it's one of the businesses where continuous profit is happening. Many people are wasting money to have fun and to be entertained, and our country will benefit from it in terms of taxes.
What I am trying to say is that people might take it negatively. They did not manage well the funds that should help the people from this calamities and now they are again adding up taxes to the people that even though they are gamblers, for them they might see that unfair. There are a lot of people that would take it like that, though I agree that casinos could really help. It is just kind of annoying how people wanted a perfect government while there can never be one.
You are saying about majority of people or just a few people who are always against the move of the government, because if that so, they will never appreciate the move of the government even if it will bring improvement to the economy, and I believe the government would not be stop with that as they will continue to work to provide the service to all people, whether haters or not.
