You are cherry-picking the numbers to fit your narrative, which is fine, but dig a little deeper. There are no black governors in this country today and there have been less than 10 in the entire history of the country. However, that is not the point.
Ask any of those people you pointed out if they have ever been called a racist name, been denied service at a restaurant or bar, pulled over by the police on multiple occasions for no reason, been denied a mortgage or unable to rent a place or have had something similar happen to them solely because of their race. Systemic racism and unconscious bias is real in this country.
Just because many black Americans have found financial success doesn't mean their path to that success wasn't an entirely different path than mine as a white man. I'm sure all of us have experienced challenges and circumstances in our life that we have overcome. We all have adapted to adversity. I would never discount how hard any of us have worked or sacrificed. That being said, I've never worried for a minute about my race impacting my path in life.
I've spent time with some very successful black men over the years. Their success is inspiring; the stories along the way are sickening.
