Obesity
4th August 2009
Megan McArdle says all that really needs to be said on the subject.
Whether a dish was dreamed up by Mario Batali or the staff at the Cheesecake Factory, preventing people from having it “for their own good” still represents an actual hedonic loss, as well as an actual loss of freedom. You may think they have some meta-self which will thank you later, but their current self has still had both its liberty and its joy restricted. Invoking the demon food scientists of agribusiness does not actually relieve you of the obligation to prove that intervening in the liberty of both the customers and the company is morally pressing.
Ultimately, the answer to “what could it hurt”? is that all actions have costs, which you cannot assume away on the grounds that those costs don’t interest you. But they should interest you, because not least among those costs is the simple fact that the government cannot do everything well. Making all sorts of changes in the name of obesity means not making others that might be more important, because we have limited political and bureaucratic bandwith. Do you want obesity intervention, cap and trade, or health care reform? You may not be able to have any of them. But you probably can’t have all three. And if you did, you’d make it more likely that the government would screw all of them up.
