There is no way to do this. Education is done on the state and district levels. There is no way to fund individual schools with African Americans going to them.
School funding discrepancies are based around bad administration, not achievement.
African Americans actually receive more funding than other races.
There is no way to give elementary scholarships to African American students. Funding individuals wouldn't change anything because the teachers and school affect kids more than being able to buy these books or school supplies.
