It was interesting one time while I was in Vegas talking to one of the locals. He said, "if you wanna know who makes the real money gambling, take a look at the size of these casino/hotels. The newer ones that open, like Wynn, Sands, etc... they are literally paid off in full in only a few months of operation." These are billion dollar prorperties! Of course casino owners want patrons to win, if they don't win something, they won't come and gamble... but they never win more than they lose... in the end!
