I'm still confused, because in one sentence, you talk about affluence bringing luxury high-rises, while in a later sentence, you talk about activist art students who want to preserve graffiti. Are the high-rises whose removal the students decry not the luxury ones, or is it a different group of activist students from those who like graffiti who are the ones who want to keep the luxury high-rises? Or are the activist art students supporters of both luxury high-rises and graffiti? I'm confused :)
