It is not designed that way because gambling should make the owner rich not the player rich. However player will keep on coming even when they know that they will lose because they are having fun there. Alot of player will want to make profit but there will be always some people like me that come back to have fun
True . Though you see.... Let me give you a different view point. What about the person who won a jackpot that changed their life ? If they had never taken a chance they never would have win. Someone will win that is a fact. You have to be incredibly lucky but for the person who wins I'm sure they don't regret it.
On the other hand you can chase trying to win all your life and never get it and if you do you would have spent more then you have won. It isn't unheard of for a first time gambler to win. It happens.
