It is a broader issue, namely: there is no such thing as doing a “thankless” job for purely altrustic reasons. This is not an issue on a small scale, but once it reaches it some critical mass we should wonder what motivates those who keep a position of authority.

(And before I get another barrage of people saying “I do it because I care about it/ I want to help / someone needs to do it”… yeah, sure, but if you are cultivating something because you happen to like the thing at hand , then you are doing for your own personal interest and it is not entirely altruistic. And that is totally fine.)
