A lively discussion is going on over at the evangelical outpost on the idea of the “sin tax,” spurred on by Rev. Sirico’s paper on that subject.
A key point to remember: once the state gets to decide which activities are immoral (but not illegal) and has a vested financial interest in them, you’ll find more and more activities becoming “sins.” Exhibit A: eating fast food.
For more on this subject, see “The Sin Tax Craze: Who’s Next?” by Rev. Sirico.
