SOME OF MEGAN McARDLE'S BEST IMAGINARY FRIENDS ARE OBESE: NotedDavid Foster Wallace scholar and Most Eligible Healthcare Blogger Ezra Klein has some funny remarks about libertarian obesity advocate Megan McArdle: "[N]one of my many talks with obesity researchers have touched on the issue of the poor being idiots. Nor do they seem to think that the obese are insufficiently aware of society's aesthetic standards. Megan doesn't have straw men here. She has invented imaginary friends for her argument."
