Your post is right, playing gambling will not lead us to wealth, even you may lose many people who are very valuable, because all you think about is winning and curiosity, it is difficult for people who are addicted to gambling to escape. they will continue to borrow money from the closest people, my advice is better not to make gambling your main job, it is very unlikely to get profit.
You`re talking about addiction but not about gambling. Common gambler can gamble without any problems - he spend the planned sum and time and sometimes wins. The professional gamblers get stable income from gambling. For lots of them - it becomes the main income. The gambling isn`t a problem, the problem is addiction of some people that believe in easy money.
