I don't think anyone is saying that diversity stems from the lack of affordability, or that they are ALL economically disadvantaged; it is a piece of the puzzle, and one of many considerations we need to include as we figure out how to be more diverse.

Several high schools where I've taught have had Panhellenic meetings in which sororities were explained to college-bound seniors and all kinds of great advice was given to them. We talked to women of every race but the black students almost all wanted NPHC. It was understandable but it's frustrating when people are going on about how we MUST be diverse and you know you've tried for years to attract a more diverse crowd of PNMs.
