If you look a bit deeper though; you'll find that greed can lead to good and bad outcomes. People make decisions because in some sense they feel like they will profit personally. That is basically the same as saying they do things for reasons. We know that most people aren't especially principled because they are regularly tested and don't make principle-based decisions. Nevertheless there is a great deal of good in the world.

Corporations are greedy, but they operate in a world where it is hard for them to enrich themselves without enriching others too.

Profit is not greed when you serve people with products and services. Or if it is greed, regulation and corruption is not another kind of greed even worse? No service, no product, no benefit for anyone.

If there is benefit in a regulation, the person imposing it is not the person paying the negative outcomes of it. Never. So no, CEOs competing cannot get more than what they generate unless they distort the market in some way.

> you get CEOs and big corporations who make decisions based on profit (essentially greed) because that is their entire purpose

That would be fine if you had hundreds of CEOs competing in a market. Unfortunately they tend to merge and create monopolies. And some people salute this because of the growth at all costs mindset.

What else in nature grows at all costs? Oh right, cancer.
