Have you never seen people decrying unequal representation in, say, tech? I've seen plenty of people make that claim and expect the distribution of groups to match the distribution in the general population. That's equality of outcome, not opportunity. It's also only really possible in two scenarios:

A. Everyone regardless of demographic has the same opportunities, talent and interest in tech

B. You force people into positions they don't want and force people out that do want them

The same goes for education, nursing, construction, sewage, fire fighting...
