Revolting as I find it personally, I can't help wondering if it isn't to this current generation of young'uns as body piercings and tattoos are to us - the next step in using your body as a palette. They've grown up in a culture where a certain amount of body modification is considered cool; why would surgically changing their body be a bad thing?

That said, I wouldn't mind it so much if it were popularized for reshaping your face and/or body to interesting or fanciful modes rather than simply trying to bring it back to an impossible social ideal.
