That's part of the problem, but it goes deeper, too:
Mainstream America not only tells whites "this is how to be beautiful." It doesn't even come up with a standard for blacks on how to be beautiful, implying that they can't be beautiful.
There are lots of ways to take this. For example, you might say, "well on the bright side, blacks didn't have to worry about needing to look beautiful, so that's freedom for them." That's a tough argument, and requires operating at a very enlightened level.
On the other hand, you can look at some of the bold black women of the 90s like Beyonce, etc. who asserted their own standards of what beauty is for black women. You could still critique that by saying, "well, America only lets black women have a standard of beauty when rich people in Hollywood can monetize it." And I believe that would be largely correct.
It's disgusting that anyone is monetized for their skin color, black/white/etc. And the real answer is to make people think for themselves and decide about whether to live someplace based on the facts or other criteria, not whether some investor could higher foreigners to show up in a commercial. The real answer here is to make people literate about the effects of advertising so we can't be fooled. It breaks my heart to see Chinese society getting made over in the image of some of America's crappiest tendencies.
