Casinos are booming at the time of pandemic so there's no downside for this since it can help people and it's beneficial to the economy also since for now the economic state is not really good and it's good to have a certain outlet where the government can take funds to use to fight the pandemic as well for the other things that needed to take care. And there's nothing wrong with regulation since if the casino is regulated the gamblers can assure that they are safety.
In terms of our country, I think there will be a negative result to this and this will be taken by the people as an insult since they think that our national government is not handling the funds that well. A lot of projects got cancelled is with the current issues and situations our country is facing, people are trying to point it all out that the government are the ones at fault why things are worsening so, yeah, there is that.
Must be your government at fault, however, if we look closely, casinos really help a certain country to grow, it will attract tourist and they are willing to spend their money in gambling especially those who are really earning well as they don't care if they have spend a lot of money as long as they are entertain.
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.
