To be even eligible of selection of being a pope is very hard. (Well technically being male and catholic is enough...) They are selected from cardinals. And cardinals in essence are the most politically successful, active and connected from priesthood. This includes also being good communicator with others in similar roles and above.

Catholic church in some sense is massive international company that only promotes internally. So at top you most likely end up with quite similar people who end up as executives in private companies.
