Living off SNGs

[Rusty Nails]

I just read spacegravy's post and there is something that has bothered me for awhile now that hopefully someone can clear up. I'm starting to wonder if it's possible to make a decent living off of sngs (excl. rakeback deals).

On the Cardplayer leaderboards there are only 30 players listed who have earned 20k in 2007 ( <$100, h/u and single table). The most anyone has made is 60k. Are these stats wrong? What am I missing?.
