Calling lotteries "tax" is only a cynical hyperbole; they are not actually a tax. People voluntarily play lotteries, whereas taxes are coerced. You do not face fines or jail time if you quit playing lotteries, like you do if you don't pay taxes. Being voluntary, lottery bets more closely resemble donations than taxes.

(Taxes on lottery winnings are a different story, of course; not talking about that here).

I'm appalled that you would suggest that it is better that people be coerced into paying for something which is adequately funded by "donations" through the lottery system.
