Comparing winner and loser with and without rake at various levels reveals the difference rake makes.
It is clear to me that the reason why the games are dried up so much must be the rake. There is simply too much money going out of the system that has to be replenished.
Essentially when we lose we feel bad. The amount we lose and how often we lose has a direct effect on how much we enjoy the game. The same is true for winning. The more we win the more we love the game.
With the rake at low stakes we are creating a big imbalance between these two, where people must eventually feel too much losing pain and quit.
