Those essentially mirror my feelings on the matter...
While I may be wrong, the president of "Jewish Community Federation of Cleveland" (just as an example) does not manage money in the same way John Paulson manages money, and doesn't need the same skills as Paulson does.
Speaking completely as an uninformed person, I'd imagine you could find a dozen or so other people with the skills to run the the JF of Cleveland, a charitable organization, for less than $650,000 per year.
