Gambling is a social crime and illegal in most countries. Gambling has a huge impact on the society of every country.
I guess the whole reason for making it illegal is to stop people from being lazy, and be upright citizens working for an honest living... because in the end he government might be involved in trying to keep some of these people on some support programmes which costs money.
Gambling creates enmity and hatred towards each other in the society. Through this, enmity may arise between the people you know. It is seen that there are many people who earn hard money all month long and only because of their gambling addiction spend money on gambling and lose their hard earned money. If a person loses through gambling, he gambles again so that he can get the money back next time. But this took a toll on his brain and he began to suffer from restlessness. Thus he cannot live a healthy normal life. So we all should refrain from gambling and spread awareness in the society about the horrors of this gambling. This is one of the main reasons for the downfall of man. Moreover, gambling is completely prohibited according to all religious laws.
I get it gambling has a negative side to it, but for some one to gamble for the extra cash means they are either not meeting ends meet and have to go out of their way to make the extra money , and unfortunately in today's world we live in to make money you need money for this if its not a day job .
And if we brainstorm on this... question should be why are people gambling more today than 10 years ago or more??
