Shareholder primacy is about forty years old rather than a natural law, and for centuries before it a corporation existed to pursue a specific beneficial purpose.

this idea is old enough that we now have a generation of people who have been raised as if this was a natural law. This is how capitalism has always been. But that's wrong. For the vast majority of the time, for hundreds of years, we have had joint stock corporations. Only the last 40 have we had this idea.
