If you look at what many consider to be the golden age of American corporations after the second world war, the notion of a “company man” was a celebrated one, and companies bragged about how they treated their employees. In that era, unlike today’s, shedding employees was not seen as an achievement but rather either a necessary evil, or a sign that the company was going down the tubes.

Over time and with complacency, we’ve ceded the territory on these things. We can say that is inevitable under capitalism that this happens if it makes you happy, but either way at one point it was a major part of the stated purpose of corporations to employ people and help them live productive lives.

Edit: I agree that what you currently have with corporations are resource devouring, profit-pursuing, psychopathic immortal monsters, but none of those things, philosophically speaking, justifies their existence as legal entities.

The platonic ideal of a corporation that owns everything, builds everything, controls everything, and employs nobody will never be fully realized, because the people it is harming will eventually rise to destroy it, or die trying.
