How do you convince idiots their blind structure is retarded?

[EasilyFound]

My home tourney games are designed to play two times in a four hour period. They start w/T2500 or T2000 with blinds starting at 25/50, increasing every 15 minutes by 50 up to 200, at which point they jump by 100, again at 15 minute interveals, until somebody wins. Occasionally, if it is late in the second tourney, blinds will increase every 10 minutes. The first game usually ends with the top two chopping the prize pool, so as to start playing again for all of those who are waiting. The second tourney is almost always played to a finish.

Even at this structure, T2000 or T2500 is not a deep stack and the blind increases force you to make moves much sooner than you'd like. But these games are beatable. The same people seem to win on a semi-regular basis.
