Another aspect of the absurdity of how negatively we treat plastic surgery is how common and acceptable cosmetic braces are in America. The vast majority of teens getting braces isn't because they medically needed them, it's just to make their teeth more attractive.
I had - chose to have - braces in adulthood, and I was very, very aware of the fact that it was in essence a cosmetic surgery. It certainly made me less judgemental about other cosmetic procedures.
