I learned of something called principal agent problem not too long ago and now I want to fit it everywhere (when all you have is a hammer yada yada). I think it works here Even when HR is perfectly operational, it favors the institution over anything else. Of course, in real life we have difficulty favoring the institution over the management. I imagine some questions are out of HR's reach though. Why is the pay highest at the top? Why should a supervisor need more pay than the people they supervise? Why can't we make all pay information public in a public company? Could we recruit, hire, and keep talented people (especially at the top) with something other than simply better pay? How "hands-on" should HR be?
