You know, the single "disrupt the norms" part is actually perfectly legit. We need that desperately in some departments. The people he chooses and why they are chosen are terrible dogshit, though, obviously.
Harris was threatening to put Republicans in some of these positions, which isn't equally bad but still a terrible idea. I personally would love to see a progressive shake-up cabinet, although my priority is always education. Depts of Education are often led by establishment figures (and even Dems have picked donors for it as a reward for service) and it's a big reason we see little movement at both federal and state levels.
There are a lot of very progressive, research-backed education specialists who would absolutely rock my world. But they're always Socialist, if not Marxist. Turns out to be a good worldview when addressing public school effectivemess, but they won't ever be picked unless the dems get more progressive.
