No need, because that's not some kind of secret. Just look at how booming the gambling industry is right now and you’ll already know. A lot of people know you will lose more. Well, there are some exceptions, those who can’t accept their losses. They don’t admit it and even blame the casino for cheating. Hmmm, as a gambler myself, why do I keep playing even if I know I will just lose more? I don’t know, maybe there’s still a part of me hoping, or maybe it’s because it has become part of my routine already.
It's obvious that the casinos are in profit, like you said, the business is booming and new casinos are coming up everyday so it's no secret that there's really money in the business. The thing is, if gamblers decide to gamble responsible the they would not make such profits compared to what they are making on a daily basis. The percentage of gambling addicts is higher than those that gamble responsibly
Yes, if every gambler agrees or decides to become responsible in gambling by just visiting the casino occasionally to just have a few minutes fun, the casino industry will not be as profitable as they are booming but it's very difficult for them not to continue being so profitable because gamblers can not be controlled or stopped from being more frequent at the casino, except for players that are living in a country where gambling is banned.
