I was tremendously insecure about my appearance when I was a child. I don't think there was anything about myself with which I was comfortable or pleased.
I really don't know why I ended up feeling that way about myself; my parents were complimentary to me and I went to a small public school that actively worked at fostering an environment free of classism and racism. We were all pretty much on equal ground.
I can only imagine how hard it is for kids these days with a near-constant media barrage of what's hot and what's not.
I wish the U.S. had taken the opportunity when it had the chance, to establish bans on advertising to young people. Seems like kids go straight from toys to Abercrombie and Fitch Jr.
Kids have a hard enough time trying to figure out who they are and what's important to them without having corporations scrambling to turn them into vapid, insecure, identically-clad, debt-bound clones.
Anyway...pretty good article : Looksism
