Very few American blacks are qualified for high tech jobs. I worked for 30 years in a world class industrial research lab with ~ 1500 Ph.Ds and another 1500 or so Masters level scientists. The number of black researchers I saw there over the years was less than a dozen, and some of them had been adopted by white parents or they came from foreign countries. There were plenty of Chinese and Indian nationals however.
But Jackson is also complaining that the janitors and lawyers are non-black as well.
