Rubbish, my sister is an HR director at a very large hotel, in charge of thousands of employees. She has saved her company millions in the decade she has been working there. In fact, she just received a promotion to supervise the HR directors at all of her chain's other hotels in the Western US.
And let me tell you, she just rolls her eyes at the multi-culti crap those in her profession have to put up with. She is definitely not a bleeding heart liberal, and in private she can hold forth with extremely politically incorrect and irreverent humor about the on-the-job performance of every ethnic and cultural group.
Obviously she has to give everyone a fair shot at a job, and keep quotas of various underprivileged groups high enough to satisfy the Federal melanin police, but long and bitter experience has taught her much about the origin of stereotypes.
