Where does the money come from?

[USGrant]

If winners are rare in poker, and losers are common, then the winners only have to win a very little from each loser to make a nice profit. The losers can drop a $1000 over a year and, because they don't keep records on PokerTracker and don't like to admit they blew a grand on gambling, will convince themselves they were "down a little" or "broke even" for the year. A winner only needs a very little slice of that $1K, and a very little slice of the other loser's $1k, etc., etc., to make thousands in that same year. It's a nice economy if you're good and you have a lot of time to kill.
