Gambling is only so addicting if you are winning unless you are just gambling for fun. When i am playing poker i don't care how much i lose or i win because poker is my favorite game.
"Problem gambling is characterized by many difficulties in limiting money and/or time spent on gambling which leads to adverse consequences for the gambler, others, or for the community."
It is only become a problem for most people because of gambling instead of preparing for the future of his family he will just keep on playing his earn money on betting, and instead of working so hard on work and getting a higher position he would just focus on getting the high bets and earn the instant cash in gambling worst thing is getting addicted and sinking deeply in it.
Make it more deeper, why this people use to gambler instead of saving for his family's future? Well of course he thinks he lacks the money to provide them future. This behavior is encourage by being desperate and poor decision that's why they decide to gamble instead of thinking other way to profit more.
