In a very unpopular move, Spain has banned appearances by fashion models who’s body mass index is too low.
Italy is considering following suit. The language in the legislation makes it clear that the purpose of the ban is to encourage healthier media images, due to the growing incidence of eating disorders diagnosed every year.
Frankly, I can’t begin to imagine the U.S. government even considering that kind of legislation. We do have a freer press here (on the surface, at least), but that doesn’t explain all the differences.
