People don't go broke in poker because the rake is too high. They go broke, by and large, because they aren't good enough to beat their opponents. It's still a skill game in the long run.

A lot of poker players (even some great players) move up stakes too quickly. In other words, they play above their bankroll.

Many poker players also have 'off the felt' problems like, ironically enough, losses accrued from gambling on blackjack, craps, etc.
