Third world country is bad (although maybe the positive racial discrimination will count them in, I don't know) but the people who get screwed by this sort of thing are also the white working class. Most employers have some (fairly rational as well as irrational) desire to screen by class, alongside the people of the upper classes knowing how to game the system of education/etc. So when you push women and ethnicities in, you push white men out, and the ones who feel the pinch are the ones already onto a loser.
