Huh? This idea is what seems naive to me.
If you treat everyone like an individual, only some things are fixed right away. Others take a very long time due to the latencies in societies and in development of talent.
For instance, the resume acceptance based on name thing is something that would be instantly fixed based on treating everyone like an individual. The big Berkeley survey puts it at about 10% now, which isn't great, but compared to the disparities in, say, literacy, it isn't anything to lose sleep over. You can afford to send out 10% more resumes. You can't afford to be functionally illiterate and unable to write one.
On the other hand, the disparities in literacy will not go away immediately because treating everyone like an individual does not change local educational opportunities very much. People suffer because of poor education.
Disparities in wealth will take even longer, because of how we treat inheritance in society. People suffer because of poverty.
Some disparities in health care will vanish instantly; others will gradually decline as (presumably) wealth catches up; and yet others won't budge at all until we notice that we need to conduct new research (which, given how many things we don't research that have nothing to do with race, may not be for a while). People suffer because of inadequate health care.
And so on.
I'd expect it to work almost by 2265, but not between, say, 1970 and 2020.
And people are really, really bad at measuring these latencies, in part because societies are really complicated and it's hard to estimate all the relevant variables with enough accuracy to matter; but mostly because people don't even bother to try. It's much easier to measure the state of affairs now.
Anyway, the bottom line is that you can't observe differential suffering and conclude that people are not being treated as individuals. There are many other possible explanations, and if we're going to craft appropriate solutions we need to understand which it is in which instance.
(Of course, you can't rule out that people are being treated in a biased way either--that happens in obvious ways all the time. But for any particular problem you have to check, and not even verify the existence of bias but also estimate the magnitude of the effect to make sure it's the dominant factor.)
