segregation in a multi-racial/ethnic world

I guess the post below deals with the morality of class based segregation. This post attempts to expand the discussion on segregation across multiple groups.

The vast majority of the literature on racial segregation focuses on white-black segregation. In this post I want to write about the complicated spatial racial/ethnic patterning involving other racial and ethnic groups. This will almost certainly boil down to white, black, Latino, and Asian (while all of these groupings are ludicrous, Asian may be the most ludicrous of them all - I think about half of the world's population could be considered Asian).
