Forgot to post my comment lol. I was gonna say that people on lower economic levels often do things to "catch up" or imitate those at higher levels; keeping up with the Jones. Embracing name brands is a great example of that. It's less a race thing than a class thing.
I like the Mad Men clip because Pete is trying to explain the American Dream to someone who it doesn't exist for. He can buy a TV but it doesn't improve his life or make him happy. So while some black people were able to buy enough things to imitate the American Dream, others couldn't...and like the guy in the clip, just ended up with a tv or something else.
