I think that everyone would like to gamble without getting addicted, but unfortunately the gambling world is made so that gamblers play and play casino or card games. Casinos are powerful organizations and they know the psychology of the player very well, and there are also dishonest casinos among them that can adjust the results of roulette or slots in order to influence the psychology of the player in this way.
I mean, when the casino gives the gambler nothing to win at the beginning, so that the gambler can come back and play more.
If they only wants to playing gambling without getting addicted, they must have strong self control and many things to avoids them from the addiction. But it will be difficult as gambling can tempts them easily and will gets them deeper in gambling without have a chance to gets out. Casino will always tempts people to comes in the next days because they will always gives the promotion that can makes people curious and wants to comes.
Both rich and poor gamblers can participate to the promotion without they can control themselves and makes more people gets addicted to gambling. They must realizes that they must limits themselves when playing gambling so they will not spends much money that can makes them lose that money in gambling and more problems will comes to them.
