I think majority of people who are addicted to gambling is because they do not understand gambling as beginners, the rules and the side effects of playing gambling excessively.
I think if gambling companies can help to giving beginners to understand gambling and addiction it will help and reduce the rate at which people get addicted o gambling, I mean good lesson for people to get understanding. Or do gambling companies benefit from gamblers who are addicted, which the awareness of getting addicted can affect their business?.
Anyways, you see, gamblers do understand what gambling is. This includes their understanding of the risk, possible effect on their life, financially, mentally, or anything negative that might come to them. But the thing is, people get addicted to gambling simply because they want to win quick money in gambling.
This also includes the enjoyment they feel, satisfaction, and even the happiness if ever they happen to win the jackpot which can be considered as a once in a lifetime opportunity due to having a low chance to make it happen.
What they don't have in this situation is realization. They understand it, believe me. But once they are up to gambling, they lose every concern they have including the possibility of losing money, their mind is more focused on winning during this time. If they have a realization, they can have a wider vision, control and avoid addiction if this happens.
