In the UK it’s not unusual for the head of a local council (running a city or a county) to make more than the PM. University chancellors make even more.
Yes but pay for both is a topic of frequent controversy. Does anyone really think it's harder to find a university chancellor, or that it requires more skill and time, than being prime minister? Or is it the result of correspondingly greater monitoring and accountability on politician's salaries vs the essentially unaccountable university system?
