I think the economy of the country will grow because of the gambling owners pay the tax and I think the amount will bigger because the owners take a big profit too from the business.
The growth of economy of a country from the people's bloodbath should not be consider a right one. I mean, people are ready to pay tax and from that tax money alone a country's economy should be developed and not from the taxes being collected from gambling houses. That is the reason many countries have prohibited gambling completely even they are aware of how big those gambling houses will be for generating income for a country.
I think there will be many negative from the gambling that we should aware so we don't play gambling in every day and spend a big money on the games.
Yes, these negative things makes gambling as a bad and prohibited one even it will be having some positive things within it. Weightage of positive things should be higher than negative things so that we accept the existence of benefits from gambling.
Some of us use gambling as a stress reliever. No matter if I win or lose I end up having a fun time and forgetting about my daily life. It makes watching sport matches much more exciting. I feel that the less stressed out we are the longer we live. I mean we all die anyways so might as well have a good time and do what makes us feel good.
Gambling as a stress reliever ? The reason I do not gamble much is because even though I feel I am catching fun once in a while, I get stressed with some headache even the more. I really do not know why that is since I do not always expect to win anything anyway, but still, it is normal to want to have that zeal since that is where the fun really is. If I wanted just playing game for the fun of it, there are several ways to play such games without gambling anyway.
