No, it's your decision completely. However when lottery supporters introduce a lottery in my state (NC) under the auspices of 'it's for the children' and there is confirmed evidence that states that
have lotteries have
higher taxes than those that don't, then it effects me as well.
Why should I have to pay a tax as well so you can get your jollies off about the infinitesimal possibility of winning a lump sum of money?
