In other words, higher-paying jobs are now, and always have been, filled disproportionately by white males. Far from being a benefit to white male workers, however, this harms them. Employers have moved millions of jobs to the Southern states in past decades because of the lower standard of living in the South. Employers have moved millions more abroad, to areas of even cheaper wages. Similarly, it would be strongly in the interest of American workers if workers in Mexico, Thailand, Indonesia, etc.
Employers never support any policies that tend to lower their profits by raising wages.
Many studies have shown that SATs, for example, predict family income much more accurately than they do performance in college. They can also afford special tutors, preparatory course, etc. In the 1930s it was discovered that men did more poorly on IQ tests than women. Then, a few years ago, the College Board decided that this assumption was false, and it was the test that was at fault. The reasoning is completely circular.
