It was easy to say if we are not in that situation and that is what OP is trying to say.
Well, that is obviously wrong because if that is right, no people got into addiction. Unfortunately, it really exists and that is the reality when it comes to gambling - many people lose control of themselves and got fall into addiction. And you are right, many families got broken due to such issues and sometimes committed crimes. But still, we can stop gambling if we really wanted and committed to doing it, yet it will take time to heal and to finally forget gambling.
There is nothing easy in Earthz even to make money is never easy. Gambling is what people do to make extra income for themselves and when we become addicted to it, it becomes very difficult for us to leave gambling since it gives us money especially for those that have earned thousands of dollars from it. Gambling addiction is something that is very hard for us to leave and it will take the effort of the gambler and the person that is trying to help. Those who are quitting gambling might be those that are really tired frim gambling especially when they are not making profits from it.
