Re: John in OK,
-- The government is allowing the expansion of gambling in order to tax it and thus gain more money to waste. --
If the taxation part is your worry, don't buy anything - at all. After all, almost everything is taxed.
The argument in favor of curtailing people's freedom cannot be based on what others do, that's fallacious. It's like arguing against letting people buy a car because someone is going to steal it. That should be the business of whoever buys the car, and so is the same with whoever does the gambling - Mind Your Own Business!
