I think that everyone who has kids should teach them about gambling at a young age. Teach them how to play blackjack, poker, craps, roulette, sports gambling, etc. You can sneak in math lessons in a way that can be entertaining, but the greater lesson should be that the house always has an edge on the player.

While gambling can be addicting, I don't think the correct response is to make it illegal. Perhaps there should be more regulation regarding the amount you can wager within a year, but keeping things underground is IMO worse for society.
