That said, this is one of the more blatant examples of social engineering through taxation. These schemes seldom work for several reasons: (1) the government is more addicted to money than Rosie is to Twinkies, and tends to spend it in places other than to address the issue at hand; (2) people modify their behavior to avoid the tax before they modify their behavior to address the problem; (3) attempting to suppress a product in demand by taxing it engenders black markets; (4) taxes, even when they are mistakenly assessed or no longer necessary, are seldom or never lifted; and (5) people like me who aren't fat and don't smoke still get pissed off when some self-righteous jackass on a power trip decides he or she knows better how to live than we do.
We could, of course, vote them out of office...only...notice how seldom this stuff is called for by elected representatives? It's usually self-proclaimed "experts" and high-minded social reformers who have enthusiasm for their chosen obsessions but absolutely no accountability for their results. "Our intentions were sound" is the pathetic bleating of a fool caught out. Usually they just change the subject.
So if your stomach ever gets empty, you starve to death?
