• I got a flash of ... what it means, now, 'you can't be too rich or too thin.' How well it works, will keep on working, because the vast majority of women will never be thin. Thin enough. How well the hope of class mobility keeps every mother dieting, and handing the diets down to her daughter, hoping the daughter may do even better. When you combine this with the fact that many non-white peoples tend to be heavier than white folks, dieting becomes a tool not only in enforcing class but in encouraging assimilation.
