I think that the video can be used as an inspirational tool, to help girls who feel insecure about themselves know what their ambitions go to.
Yes I do agree that looks a superficial but powerful.
No, because some women and some girls look up to these models, and aspire to be and look like them.
Because their whole career is about their looks and all they worry about every second of their lives is 'how they look?' or 'Do I look bad?' because that's what they all have to worry about... Constantly.
Me personally... No. Other people that look better may receive more positive attention from society.
Not so much, but people do call me 'Chinese' constantly just because I have narrow eyes.
