I gotta go with a yes on this one. The Criterion Collection version is really amazing and worth getting if anyone is interested. I recently wrote a review and I'd like to share a part of it:
I always thought Claire was pretty deep of a character actually. She had arguably the most societal pressure by her peer group, was pretty sophisticated (sushi!), and masked her own sadness in her social stature and class. I do hate the ending where her and Bender get together (don't even get me started on Andrew and Allison) and I think that ending is actually kind of phoned in because they needed something uplifting. I think that probably speaks more about audiences and their expectations than what John Hughes actually believes. However, Bender calling Claire a "fat girl's name" is kind of brilliant if not abundantly obnoxious. That's the one thing Claire would be really superficial about and actually really bother her. While I haven't been around teenagers in a while, but they do talk like this as they do say some rather obscene stuff.
I think Hughes knew what he wrote, and thus we get a lot of white characters. If Long-Duck Dong is any indication, maybe it's a huge blessing this film is basically wonder bread.
