modern immigration from Africa

This week we discussed the slave trade and it's impact on Africa.  The article I am posting states a curious title.  More Africans have immigrated to the United States in the recent years than came over as a result of the slave trade. The most interesting point the article makes is that the group of immigrantsnow being admitted is being selected for by ambition. The recent immigrants from Africa collectively had a higher percentage of college degrees than did their American born counterparts.
