This is an interesting set of remarks. Again, I was looking at this through the lens of what I consider to be a successful policy on taxing cigarettes, and through a political philosophy that is quite close to the approach in Nudge: http://www.amazon.com/Nudge-Improvin...9967134&sr=8-1
Of course, again, I'd be content if we merely elimitated our massive subsidies for corn and soy-based products (like HCFC-sweetened drinks). (On that note, I find the comment on rum-and-coke funny, since the rum portion is heavily taxed and the coke portion heavily subsidized).
Also interesting the comments on obesity being an individual moral issue. To my mind, it's not, either:
1) Are we any less individual moral now than we were 100 years ago, or 100,000 years ago? (note that everyone thinks the previous age was the golden age, but really?)
2) We all pay for the increased burden of diabetes and cardiovascular disease in our taxes and health care premiums
Or, to put it a different way, our modern health care crisis is a consequence of the society we live in, including both governmental and societal norms, and we need to change both, with a lot of undoing of stuff that we are currently actively doing to mess things up (subsidizing HCFC, corn oil, and grain fed antibiotic resistant beef), and lots of nudging the other way.
I, of course, take all the points about how wrongheaded the current governmental/scientific "consensus" on diet currently is as well.
