There is no question, though it's not acknowledged enough, that black Americans have made greater gains, over some of the highest hurdles and in a very short span of time, than any other racial group in mankind's history.
What's the evidence? If black Americans were thought of as a nation with their own gross domestic product, they'd rank among the 20 wealthiest nations. It was a black American, Gen. Colin Powell, who headed the mightiest military in mankind's history. A few black Americans are among the world's wealthiest. Many black Americans are among the world's most famous personalities.
The significance of all this is that in 1865, neither an ex-slave nor an ex-slave owner would have believed that such progress would be possible in less than a century and a half. As such, it speaks to the intestinal fortitude of a people. Just as importantly, it speaks to the greatness of a nation within which such progress was possible. That progress would have been impossible anywhere except in the United States of America. The challenge that lies before us is how those gains can be extended to a large percentage of black people for whom they appear elusive.
