Most museums now say they are committed to social justice. So why are so many laying off workers en masse?

I'm just going to repeat myself. From http://iwantanewleft.typepad.com/i-want-a-new-left/2020/03/adjuncts-and-the-left.html :

After all, there was nothing stopping institutions from giving higher pay to adjuncts and lower pay to tenured faculty. Nor was there anything preventing tenured faculty from banding together and setting up a fund on their own to which they would contribute that would be redistributed to adjuncts. The fact that neither of these possibilities ever happened is what made me turn away from socialism. After all, most faculty members believe in the redistribution of wealth, and if you as someone who is comparatively wealthy find yourself in a situation where some of your colleagues are much poorer, it behooves you to start doing some redistributing. However, it never seemed to occur to tenured leftists that this is something they ought to have done.
