Lottery tickets at least avoid the worst aspects of the real time feedback that things like slot machines can give. Though scratchoffs certainly get closer.
I do hold out some hope that in this pendulum swing we can land at least for a while on banning state sponsored gambling, though. It'll come back. Too appealing to keep down forever, unfortunately. I like to say it's a good exercise to sit down and really think about the difference between "organized crime" and a "government" but when a "government" does things like zealous defense of its gambling monopoly it does rather weaken the distinction....
