Interesting. It seems to be a similar story in multiple states. I oppose state funded gambling, and this is one reason.
That effectively makes it a tax on the innumerate.
People are going to gamble though, so the state might as well take a cut as a way to discourage it.
It's fairly well established that rather than discouraging gambling, the result of government endorsement and taxation is a net increase in gambling.
I think I've also seen some analysis that after about a decade, the increase in gambling behavior is also correlated with less taxable income from citizens, higher consumption of alcohol, etc., which amplifies the regressive effects.
