"The “exchange” in cultural exchange suggests you give something in return for having taken something. If it’s culture that’s taken, then presumably what’s given back is the art. In which case the difference between appropriation and exchange, to be (maybe absurdly) logical about it, would have to lie with an assessment of the value of the art itself. Of course we can’t really quantify the value of what is taken or the value of the art, but that would be the logic. The more you take, the more you have to give back — the better the work has to be. Maybe when we say it’s wrong to take something, we really mean, What you’ve given back is far too poor, too mediocre — it’s bad art. I’ve never heard anyone accuse the hip-hop group Wu-Tang Clan of appropriating Chinese culture. This may be because I haven’t talked to enough people. But maybe it is because the music that came from a group of hip-hop kids from Staten Island who watched a lot of kung fu movies in trips to Times Square was that good."
