I'm saying that both normal body weight and high earning potential are caused by a third factor, coming from an affluent background in the first place. - OK, Bride, I didn't clock that and can agree with it. To an extent. But I believe prejudice is still at the root - even from the successful woman's early childhood, when she was fed less than her brother.
Just did a very quick search for some figures - didn't find the ones I was looking for, but thought this interesting:-
Skinny women got paid substantially higher salaries than heavier women, yet this relationship was much less pronounced at the higher ends of the scale. Meaning that a female employee weighing 50 kilograms would get paid substantially more than someone weighing 60 kilograms, but the difference between 70 and 80 was much less severe. That?s probably because ? as Dan and Tim put it ? ?the social preferences for a feminine body have already been violated?; you?re either skinny or not, but once you?re over the (rather extreme) threshold, we don?t care much anymore about the number on your scale.
Yet, this relationship looked very different for men. In contrast to the women in the sample, men of moderate weight would get paid substantially more than skinny men. But such a man of average weight would also get paid quite a bit more than an obese person. Hence, being skinny for a woman would mean more dosh, but for men it would mean less money ? all in the order of magnitude of $10,000-15,000 per year.

This is not a Daily Mail dipstick poll. The study looked at weight and income data on 11,253 German employees and, in another study, on 12,686 American workers; the latter who were measured no less than 15 times over a period of 25 years, to also see how change in weight was related to changes in income.
