What's the REAL reason(s) so many "top" players are busto?

[swope]

how about; poker is nearly impossible to beat long term? its gambling, brosephs. stu unger was a savant, he could beat the game. phil ivey, chip reese, etc, im awed by their ability and their stamina and their discipline but i guarantee you that they go broke just as fast as anyone else if the rivers dont go there way enough times.
