Would working-class whites be so furious about “political correctness” if they were among those whose challenges were recognized? Not likely. We won’t know how much racism falls away until we stop insulting working-class whites and try including them within our ambit of responsibility.
Perhaps I've misunderstood the prior use of "responsibility." I agree that the upper middle class needs to change the frame of structural injustice, but I think addressing the broad working class common issues must precede race and other identity-specific disadvantages.
