If you really look at it correctly, they probably lost the top 10% simply because of Affirmative Action. The best are not hired, therefore, the lowest 10% are worst than you think. As for Gladiator Pit analogy, hiring is based on quotas so White Males compete against White Males, Black females against Black females; Hispanics, Asians el at. men and women within their racial groups are quoted within the diversity of the workforce. I would lay odds that either Asian or White Males are the most competitive of all the groups followed by Asian or White Females; Asians would follow second. Jobs have become mandatory for racial quotas. Today the majority of hiring is going to LGBT to ensure their balance, and for practioners of Islam.
Any place that a white male without some kind of very unique skill can find a job now is probably a hell hole where those who are given preferences refuse to work. I checked my “white privilege” and as nearly as I can determine it ceased to exist sometime in the sixties. I think I’ll have a DNA test to see if I am one tenth of one percent something other than Anglo-Saxon or Norman so I can claim a real privilege.
When you get rid of the bottom 10% every year it kills a company. Sure maybe that year you get rid of a bunch of dead weight, maybe even the second. But you’re deliberately grading on a curve. Eventually that bottom 10% are actually good employees, they just happen to be the “worst” left. Not to mention how this kind of fear drives employees out, and the uncertainty distracts everybody through review month and kill productivity for everybody.
