But what if people stop aiming for profit and gamble only for fun, what do you think would be the impact on the gambling industry?
Will we still see it growing or will the industry shrink?
This is not a realistic scenario. People have two motivations in playing: to have a chance to make money and to be entertained. There may be a drop in profit, but the casino can still operate as long as people continue to wager. Some individuals will wager a significant amount of money simply to satisfy their ego, regardless of their motivation.
I have read gamblers who are not playing to win money but to play just for the sake of playing and to boost their ego and confidence, so casinos will still be profitable, if that scenario ever exists.
