This is the key thing. Publicly traded companies effectively have no head. They are driven by the legal mandate to pursue the profit motive for faceless and litigious investors. Yes the ceo/chairman of the board usually has a controlling share, but some rando who has one share from Robinhood can sue if they think the company is not operating with their interests in mind.

Small businesses and private companies can also be evil, but at least everyone who owns the company knows each other. They may decide to take a loss if they think it would make them look better to the public in the long run. Public companies cannot. They are expected to gobble up as much profit as they can. And when they can’t make more profit they are gobbled up by other more vigorous companies that are owned by the same investors. It’s a sick game that is eating the world and humanity to death.
