no its not like that, these people get plopped into positions of power, and alot of time theres no good way to assess their performance

There are plenty of good ways to assess performance of CEO. However the important ones can only be run 10-20 years from now and so they are not helpful.

Is there? I don't see many control group companies working in absence of a CEO.

Right it’s like venture investing c very hard to evaluate short term
