Many things that are interesting to think about are also discouraging, at least initially. The “tragedy of the commons” is one such subject. The commons is communal property - imagine a square of pasture where everyone can graze their livestock. Each individual is allowed to add another animal to graze, because the commons belongs to everyone. Of course, it’s in the public’s best interest not to overgraze the pasture, but at the same time, individuals aren’t punished or fined by incrementally adding to the number of animals grazing. The tragedy of the commons reflects the tendency of individual, or local incentive, to trump global concerns: it seems that the commons generally tends to lose out, to the extent that there aren’t protective provisions in place.
In countries where taxes are collected, some of the revenues support public benefits. But in no such country is it optional to pay taxes, because the group of individual potential taxpayers would succumb to the tragedy of the commons.
As a department chairman, most of my work is in a supporting role for my department. I do some required tasks (reports and such) so that others in the department don’t have to. (Other department chairs choose to delegate this kind of work to other department members - that doesn’t really matter to my point.) But I am also the go-to person for faculty requests - everything from preferential consideration on course assignments to course release time, travel funding, student or colleague-related problem solving, or other special requests.
I do what I can to help the department as a whole function effectively and efficiently, and I also do what I can to help individual faculty members succeed in their careers. But I am the commons. I serve all, but each has some incentive to try to get something from me, and once I have been overgrazed, I will have no resources left to help the community.
I can see that I must generate my own protections in this type of service role, because no one else has acted to create them.
