But isn't diversity the key to success?
The research makes clear that there is something unique about the obstacles black males face. The gap between Hispanics and whites is narrower, and their incomes will converge within a couple of generations if mobility stays the same. Asian-Americans earn more than whites raised at the same income level, or about the same when first-generation immigrants are excluded. Only Native Americans have an income gap comparable to African-Americans. But the disparities are widest for black boys.
