As the Atlantic's tribe of online voices has expanded, it naturally supports a range of views, opinions, subject matter, personal obsessions, styles of argument, and so on. Sometimes we have unintended overlap -- as when Lane Wallace and I were independently impressed by the same innovations on display at this week's Oshkosh air show. Sometimes we have straight-out differences of opinion, as here and here, and now between Marc Ambinder and Megan McArdle on whether obesity is a real public health problem or another instance of nanny-state moralizing. McArdle's posting is here, and Ambinder's reply is here.
I am 100% with Ambinder on this one, and would be 1000% with him if that term weren't assumed to be sarcastic. It is notable, though not noted in the original item, that the obesity-skeptic Paul Campos with whom Megan McArdle conducts an extensive, sympathetic interview is a law professor rather than a doctor, public health official, epidemiologist, etc (which of course doesn't disqualify his views but should be mentioned); and that the word "diabetes" does not appear in the discussion in which he pooh-poohs the public health effects of obesity.
If you've been around the US as long as I have (ie, if you're as old), you have seen very significant aspects of public-health behavior change in your own lifetime. When my dad went to medical conventions in the 1950s and 1960s, most of his fellow doctors smoked. By the time he retired in the 1990s, very few of them did. For better and worse, smoking has become a class-bound phenomenon in America: better for the people who don't smoke any more, worse as one more disadvantage of being poorer and less educated. The difference is startling and obvious if you spend time in, let's say, China, where many more people of all classes smoke. As individuals, Americans have the same human nature as they did 40 years ago, and the same nature as people in China. Will power, compulsions, addition-seeking instincts, etc. But their overall behavior about smoking has changed. Some individuals did not or could not change their behavior. (One of my grandmothers, who had started smoking as a flapper in the 1920s, died of a horrible case of emphysema, sneaking cigarettes on her last conscious days.) But average behavior changed dramatically. In my view, no sane person can deny that public anti-smoking campaigns have made a huge difference.
