Texas schools need $X funding. The Texas Lottery was meant to add $Y dollars to education. The lottery was sold to the public as meaning schools would be funded to the tune of $(X + Y) each year.

Instead, the state funds $(X - Y). Instead of supplementing education funds, the lottery supplants it. And it’s the exact same thing with tipping culture.

(I’d bet this is how most state lotteries which fund education operate.)
