Rather daft comment.

And these companies haven't "gone crazy". There is zero evidence for that.

Also, exact quotas is discriminatory by definition. You are, by definition, hiring and/or not hiring somebody because of their race, which itself is becoming a rather tenuous concept in itself due to globalisation (mixing of races).

Without these sorts of rules than it's a free for all. I have zero evidence except life experience to say that if people could hire their preferred tribe, they would. The homogeneous work culture alone would probably be very effective. But wow, what a horrendous world to live in. I mean, seriously, you kids have no idea.

That's discrimination based on culture, not on race, though.
