Everyone knows the game is rigged, but they also know that they will still find a way to win with heart and determination and all that BS people feed themselves.
Some people know just how far the rigging goes, and they do their best to keep it going, usually because through accident of birth they are on the side with the power, or else a misguided hope they can join said lucky ones.
A few refuse to play, despite knowing the costs involved.
Because it's not enough to refuse to place your bet. You have to flip the whole table.
