You have a mistaken idea that community is about repaying.

We're not in a just world, the community is supposed to be about bettering everyone, but of course there are traps like sports or people who ignore it.

The honest rule is to pay back more as your ability to increases.

The teacher does not have to be directly paid back by his students, it is enough that some of them will produce a generalized return, trickling down and around.

However, we're all too local for that to really work. Hence witness flight from cheap or rural areas to cities, draining resources.

None of this requires conflict. It just requires pure indifference. Teams can cooperate too.
