The problem is not about baggy pants. The problem is about a self-defeating culture that denigrates success through hard work as "white", demeans education, shouts "f[inks] the police", suffers from broken families, etc. No sane person would deny that racial oppression is what caused this problem, absolutely. But that doesn't mean racial oppression is what is perpetuating it.
Please, guys, read the book.
Some of that is because some folks don't succeed at work, or school, so they put it down as a defense mechanism. Who wants to suck at something that's important to not suck at? And that gets back to the crappy state of the schools, which gets back to why I am so militant on that issue - having poor schools in poor neighborhoods, with no alternatives offered, is the single most evil thing this nation does at the moment.
