one of them is big oil. they lied about climate change.

The system is the problem here, because it incentivizes these kinds of corporations to do these things.

So by the very nature of capitalism, all corporations.

When you have a boss "ruling over" a worker, that is just barely different than living as a serf. The difference here is you can choose your boss, but inherent in the system is that workers don't earn the full value of their work (surplus value), otherwise it wouldn't be worth it for the owner class to hire anyone.

Worker-owned cooperatives are pretty cool, though. Would be nice if all corporations were forced to be worker-owned.
