You’re being downvoted and it’s an intriguing question.

Corp is gonna corp.

The fact is there is an externality that exists to be taken advantage of, and it can try to be corrected in a few ways. Punishing the corp with taxes, regs etc is only one way

It was actually a stretch at first to get people to throw packaging away. You can find ad campaigns comparing picnics with reusable containers to picnics with disposable containers for example, so you could argue that disposal didn't come naturally but rather was socialized by people who wanted to make and sell a lot of plastic.

Definitely, if what a corp is doing is legal they are going to maximize profits. It might not be ethical, but corporations are businesses created to generate money.

I'm sure most of us here could find something unethical about their employer if we looked deep enough. That action might even be a product of globalization or the society and the only way for the corporation to exist is to do that unethical thing.

Its on the government to protect the people and the land. If plastic is an issue they should force the producers to do something about it. They would then need to increase the cost of the product, which could force people to use cheaper alternatives.
