This is actually not the case: https://en.wikipedia.org/wiki/Dodge_v._Ford_Motor_Co. However a look at Henry Ford’s personal priorities shows that there’s a be-careful-what-you-wish-for aspect to this (also arguably visible to a lesser extent in eg. Mark Zuckerberg’s dual-class-structure-enabled control on Facebook—and in Musk’s de facto control over his rambling empire).

I feel like this just furthers my point. Over 100 years ago a court ruled that companies have to operate primarily for the benefit of their shareholders. That is the regime we have been operating in ever since. You may get some eccentric cases like Ford or Zuckerberg from time to time when they don't operate in the interests of shareholders, but it's far from the norm.
