I think that casino is like a sport event or cinema. You pay money for emotions, for fun. When i go gambling i decide before it that this money i spend. If i win smth - it is just additional bonus, additional emotions.
And if someone wants to get money for life from casino - it is a big mistake, often it means that this man will lose all his money without any result.
but I'm sure you've also seen, a gambler who plays at the casino every day. not just spend enough money. but spent the assets owned.
I've seen people who are addicted to casino games. and it's really scary. not just a game for entertainment.
I play at the casino. but like you said, I was ready to lose the money I could afford. and when it runs out, then I will finish and exit the casino.
