I’m sorry you’re under the impression that the economy is controlled equally by tens of thousands of corporations. Its much more like 2 dozen control nearly all money that presently exists. They wake up everyday and fix prices. They’ve been doing it a lot ever since 2008 and the utter downfall of consumer protections. I also have no fucking clue what you mean when you say that not fixing prices is in their best interests?? Like, you realize that by price fixing they make billions of dollars more than they should be? How tf is making even more money not in the interest of a corporation? They literally profit off of wars. Any possible thing that increases the amount of capital they generate is in their own best interests. Even employing children, or slaves. Capitalism is designed specifically to be exploitative of as many people as possible to generate as much capital as possible.
