I disagree. Although I'm not in the business, my understanding from wide reading in the topic is quite the opposite. Casinos make money from "whales," who may or may not end up ruined to a man, but who are certainly losing enough money to ruin an average bettor. The guy losing $500 at BJ once in a while (and once in a blue moon winning some back) is the "economy coach class super saver" flyer. Yes, enough of those small fry help defray the fixed costs of the flight. But it's the last minute business class flyer that brings the margin. Similarly, the real money for the casino is in some mix of 1. problem gamblers, almost by definition, and 2. money laundering.
