I would say there are cheaters at every level. It's just more galling when the people at the top cheat, because they ought to be able to get by honestly.

You must be joking. I would have a hard time believing anyone at the top got there honestly. I'm sure it happens but it must be vanishingly rare. Take Lance Armstrong: I doubt he set out to be a cheater, but when everyone else is doping the only way to compete is to dope yourself.
