Gambling arms race

This is not to pass judgment on gambling. It's just a comment on the gambling arms race among states. This is from the Christian Science Monitor:

Three decades ago, there were no casinos outside Nevada, and only 13 states ran lotteries. Today 19 states support commercial gambling in densely populated markets near interstates, 28 states host Indian casinos, 41 run lotteries, and 43 allow track-side betting. Even so-called riverboat casinos have expanded rapidly as states lift wager limits to permit casinos they couldn't sanction on solid ground. Only Utah and Hawaii still ban gambling.

No matter how you feel about gambling, it's hard to argue that the arms race goes on. Where is the saturation point, and what do we do when we reach it? I still wonder if tables games at the four West Virginia racetrack casinos will be as great as proponents say it will be. I could be wrong, of course.
