Having spent six years and change teaching college as an adjunct, and having a white Ph.D. friend who had to go to Saudi Arabia to get his one and only full-time teqching job, I have to doubt that. While even in the humanities, black Ph.D.s have both predominantly white and predominantly black institutions chasing after them to hire them, white male Ph.D.s must desperately search the entire planet for full-time teaching jobs.
...and the people making the hiring decisions may think that a black person will be more effective with their students than a white person would be.
That's illegal. It's also untrue -- studies have shown that black instrutors are no more successful at teaching black students than are white educators. As a matter of fact, after blacks ran off white teachers and administrators from their public schools, and demanded new, black public colleges with black professors and administrators, black academic achievement collapsed.
