edit: I didn't even mention that they also must maintain enormous research operations, some of them performing research that is literally the bleeding edge of human knowledge. Like imagine trying to helm a corporation that is simultaneously invested in multi-billion dollar government grants for deep-tech R&D, alongside a portfolio of ~15 hotels, a minor-league football team, an urgent care, a landscaping company, and something like 10-20 high schools of students. Not to mention libraries, museums, gyms, food, etc. And god help you if your campus is more than 50 years old, because the cost of maintaining all those buildings are going to be insane. If you were able to do this all without bloat or graft honestly I think you'd a generational genius in management.
