The idea of a standard bar and so on does sound like it would interfere with such a process.
I always did find it interesting that US notions of anti-racism required treating individuals not as individuals but as racial representatives. It’s a local quirk of the culture of the land, I suppose, that one’s primary identification here is one’s skin colour.
I agree that we should just stop using race everywhere and we should crack down on it -- but I think college wouldn't be where my energy would be... actually the military is where I'd start. And oddly it's the place where race based affirmative action is still permitted (military academies - where it benefits minorities) and in its halls (where I've heard that it has a strong white supremacist bent). The reason is because what is happening in colleges is more reactionary -- fix the catalyst and the arguments for the reaction largely go away.
Unfortunately, the lost signal wasn't replaced with anything. (I don't know what could replace it. It's an incredibly hard problem. )
