The schools have needed air conditioners forever. This isn't some new development. Utah is among the last in the nation when it comes to spending on schools. If you want to raise taxes, raise them. It doesn't mean we can't have a lottery. But I'm sure if there was a statewide vote that said "lower taxes and legalize a lottery" or "raise taxes and keep lotteries illegal" the lottery would be legalized by a landslide. People might historically support a progressive tax, but people also historically (and currently) support lotteries in almost every state.
The economics of it right now say millions of dollars are leaving the state every year. It is all going to Idaho, Colorado, and Arizona. Those states get paid every time a Utah resident buys a lottery ticket there. They also withhold state (and federal) income tax from the big winnings. And they keep all of the unclaimed winnings (not big enough for someone to drive all the way there to claim).
It's not a theoretical "if we legalized a lottery and people played..." It's a "people are playing it right now so we might as well keep the money in this state."
Isn't that simply due the the large rnumber of children in Utah? I live in a southern Utah town and it has around 7 elementary schools. I lived in a town in Missippi around the same size and it had 1 elementary school. So Utah can be spending a crap load on schools but the dollar per child is crap.
Or does Utah spend less starting out?
