OK, five drab, mirthless pages in I've found a diverting observation:
I suspect that part of the self-conscious community thing here has to do with space. Rural Midwesterners live surrounded by unpopulated land, marooned in a space whose emptiness is both physical and spiritual. It is not just people you get lonely for. You're alienated from the very space around you, for here the land is not an environment but a commodity. The land is basically a factory. You live in the same factory you work in. You spend an enormous amount of time with the land, but you're still alienated from it in some way.
I grew up in a broadly similar environment, so that's familiar ground to me. Jonathan Meades disposed of a similar point quickly in
Double Dutch in the midst of a few score more provocative, funny, resonant ideas.
I will continue to haughtily ignore DFW's non-fiction, no one will be alarmed to learn.
