Nanny Bloomberg is asking the federal government to forbid soda sales with food stamps in New York City. Now, when Food Stamps were first introduced in the sixties, soda and snacks (somewhat arbitrarily defined, of course) weren't food-stamp-eligible. At the time, it seemed a perfectly sensible limitation for a program that was, after all, designed to provide basic nutrition.
It wasn't a health restriction -- soda pop was simply considered a luxury. For Bloomberg, though, it's just another way to control people's lives according to what he thinks best for them.
