Is the pornography industry responsible for lowering the moral conduct of Americans. Since the 1970's it has been illegal to import porn into the U.S., so the pornography industry is actually one of the few industries which is protected against foreign competition. Primarily based in California, porn generates $13.3 billion per year for our economy. My question is, is it worth it? Are we paying more than we realize? Moral decay has vanquished civilizations before, and history has a way of repeating itself.
