It's actually pretty simple - money, power. Corporations are amoral machines; if there's something that brings profits and they can get away with legally, some corp will eventually do it (same seems to apply to small companies).
> Instead of thinking from "corporations vs. us", a better approach would be to think of humanity as a single entity.
Thinking like this was always the hallmark of my life. But the more I interact with actual people, and not just high-school friends but random people; CEOs and coworkers and shopowners and cleners - the more I realize there is a split there. Some of us think of humanity as a single entity worth caring about. Others don't give a fuck. They think of "me, family and friends vs. the rest of the world". Which makes it easy to justify fucking "the rest of the world" for profit. I don't really know how humanity is to reconcile those two worldviews.
