I could hardly agree with you any more, very nice post. I think you nailed what's wrong with the whole thing, and why so many women of all types tear themselves apart and even kill themselves over an "ideal" that just isn't uncommon, it's entirely unrealistic if not impossible.
Which is the way they want it, I guess. It's hard to commoditize what isn't rare, that's simple economics. So, they push an impossible ideal, and select the ultrarare few who can be modified to fit it so that they can mine them for the artificial value in their rarity. And if their ideal suddenly became the norm, they'd probably change it.
I guess what you've pointed out is that the industry isn't about beauty, much less any kind of caring about the consequences of their image-mongering on real women, they're about profit. Which only reinforces my original point that it's sad that so many women judge themselves so harshly against their standard.
Great post. Like I said, I think you nailed some serious truth. :)
