Money is a "Pay to Play" system or club.
Added to that are increasing membership conditions (which can be ultimatums or threats)

Many people pay because there isn't really another club or faction to join.

And people's principles can quickly give way to any ultimatum close to "you in or out?" Or "do you want to lose your ability to play with all the other players in the world and risk something else?".

The answer is often no, even if the casino is cheating you.
