Ask the question this way.
Are Brittany McKnight and John Wilson more employable than Lukwesa Nakazwe and Hijani Lungo?
Yes and it is obviously about race. Why? On average, Africans immigrants are more highly educated than native born Caucasians.
It's not about education. It's not about statistics. It's about racism. There have been studies where researchers submitted resumes with identical education and employment backgrounds but substituted "white sounding" names for "black sounding" names and the ones with the "black sounding" names were half as likely to be contacted by prospective employers.
With the same education and the same work experience, "Je'Marcus Johnson" is half as likely to even be interviewed as "Mark Johnson".
