Yes and No. Yes, it’s not only corporations and we must act ourselves.
No, it’s the rules that set the game. Corporations play within the rules. Politics is owning and can change the rules. The society and corporations will follow accordingly. If we really want to change we can. Look what happened during Covid. In retrospect, some insane rules (eg Germany kids not allowed to enter playgrounds. Kids couldn’t play to save the elderly). However, society obeyed to those rules.
It’s not us, it’s the rules that must change. In my view this should be the priority.
