Those would-be students are dead, either Trayvonned or aborted before they could draw a breath. The federal and blue-state governments have destroyed the black family, thus ending the chances for millions of would-be George Washington Carvers. Instead, feral black youths kill one another and prey on others in an EBT-fueled cycle of violence, all charged to the Federal Reserve’s bottomless credit card.
The American black family has been a failure since the 1960's. Before that they were, more or less, on a par with other families. White families were able to make it through those awful 60's years (more or less) but the more fragile black family had a TOUGH time.
