This was a Martha Stewart publication with a female editor and writing staff, which only makes the question more perplexing -- Why is this impossible, unattractive standard held up as ideal for women? Do some women actually think this look is desirable?
Two things pop into my head to your question.
1 this is a consumeristic socitey. We have to be chasing carrots that we cant catch.
Not being able to be thin as a model but trying to be thin as a model is good for all kinds of businesses.
Food, clothing, exercise, gyms, the magazine industry. People by pictures of the magazines so
they can look at the models and fantasize being that thin, while they drink their diet cokes
with their big macs.
The second thought is that we are all in a computerized matrix run by machines and fat people
looking at thin models creates energy, stress, tension, for the batteries.
