the reason is not particularly relevant to the point I was making; Just to be clear, I disagree with your assessment of the reasons for the disparity in pay, my own life experiences and education cause me to assign the disparity largely to irrational bias, but certainly I don't know of any good evidence either way. I'm just saying that whatever the reason for the disparity in pay, adding a group of workers who make less to the average is going to push down that average.
