Generally yes. It is a defacto voluntary tax on lower income citizens. Lottery's are immoral and unethical and should be stopped.

Imagine if the gov cancelled lottery's and then increased taxes on the people who spend the most on lotto tickets to make up the deficit?

My favorite part are the states that run lottery's yet outlaw gambling. It's fine if the politicians run a gambling racket and get to pick the winners and losers of the state monies spent to run them but by god no private citizens will be allowed to do it because that would just be encouraging gambling!
