> How sick is it, if true, people are purposely pitting people against each other for the sake of getting away with something.
I don't know if "purposeful" is the right word. More like the emergent behavior of lots of people in large organizations working in their self-interest. Imagine you're a young Harvard graduate entering Wall Street. In the olden days, you would reconcile yourself to being "the man," and convince yourself that the working classes deserved their condition due to their moral shortcomings. Now your schooling has filled your head with notions of justice and equality, but you're still "the man" and your personal incentives haven't changed. Committing to "equity" while condemning working class white people for their moral failings allows you to square the circle and make minimal changes that could affect your own self interest.
But the consequences of that attitude downstream are dire and indistinguishable from a deliberate effort. When a white manager commits to "equity" and condemns the white line workers as "racists, sexists, and homophobes," that not only divides the working class amongst itself. It also inverts the traditional cultural understanding that the line workers are "the good guys" and the managers are "the bad guys"--further depriving the working class of what little political and rhetorical capital it used to possess.

You see this acutely among first versus second+ generation Asians. I relied on meritocratic systems to get ahead after my parents immigrated here from Bangladesh. I went to a public magnet high school, engineering school, and law school based on my test scores. I don't know anybody on that side of the ladder who thinks there's anything wrong with using testing to identify talent. But my kids go to a private school where we have a second winter break for ski vacations. Whatever system replaces standardized testing, I will know how to work it and my kids will be fine.
