I think the key factor you're missing is that this issue is deeply political and historical. This isn't just a question about what's on the label, ie. black people being hired proportionally, but also about whose fault/responsibility it is to fix. If you say "should we look at other parts of the pipeline?" you're aligning yourself with the political faction of "it's black peoples' problem, not society's." If you advocate for hiring quotas or similar, then you're aligning yourself with the "it's society's problem, not black peoples'" Of course real solutions to the problem are somewhere in between, and you can argue until you're blue in the face that suggesting looking at other parts of the pipeline is NOT actually saying it's black peoples' problem, but it won't matter. You're in a space where there are powerful political divisions with the entire socioracial history of a large population at sake, and you're going to ruthlessly rounded to either US or THEM. That's a big part of the reason it's so hard to talk about, and harder still to solve, even before you get to the fact that even without the deep psychological and political baggage it's already a super hard problem.
