So being the whitest girl on the planet, I'm positive that I'm the wrong person to do this write up. But, The Root has this really interesting article on the tensions between Black students whose parents were born in the states and immigrants/children of immigrants. In "Among College Students, Parsing 'Regular Black' and 'Ethnic Black'", Diana Ozemebhoya Eromosele discusses "the lengths to which some students go to distinguish their brand of blackness."
She writes how lumping the two groups together often doesn't make sense, as non-native born Black students come from many distinct cultures and often come from families that are quite privileged in comparison to many native born students.
some of their parents actually had certain economic advantages when they came to the United States, such as student visas, and certainly ideological advantages, such as having been reared and exposed to majority-black governments and societies, which no doubt does wonders for one's sense of self-determination....
And she brings up this old discussion of whether these students are taking away affirmative action slots from native students, as they make up a disproportionate ratio of black college students at elite universities.
...at top-tier universities and Ivy League schools, where a 2007 study found that approximately 40 percent of black students had at least one parent born in a foreign land—nearly half of the black-student population. Meanwhile, only 20 percent of black college students across the nation have at least one immigrant parent...
Despite being about Ivy's, Eromosele's article very much gelled with my experience of being in the CUNY system for more years than I care to admit. We seem to have that over-representation thing going on, 'specially in STEM, and magnified at the PhD level. It also crosses ethnicity, which makes sense-out of state/foreign student tuition is so damn expensive that you basically have to be privileged to afford to come here.
