Pretty sure gambling is only a waste of money if you suck. Have a friend that's made millions off blackjack. I don't think he'd be better off having saved.
And no, he didn't get lucky, he can consistently walk into a casino, cardcount, and walk out with $200,000 or so, and then repeat 2-3 times till he gets banned when they catch on that he's not going to be profitable for them to continue serving.
Much like me betting I beat any of the three of you isn't wasting money, it's making money.
