[opportune]

the vast majority of revenues from gambling comes from problematic gamblers. Nobody is saying we should make it illegal to go to the casino for a night every few months but the gambling industry doesn't really make money off those people except as a gateway drug. I doubt you could gain insight into the lives of a problem gambler and tell me it's even "fun".

I think gambling is like booze in that respect. There is hardly any tail at all in the distribution. 5% of the drinkers are consuming 95% of the booze.

Edit: Prostitution is probably also like that.

Basically the three things that underpin Atlantic City right there.
