I’ve always been leery of people obsessed with a single issue, who see the world entirely through some narrow prism. Marxists tend to be like that, if there are any left. Single-issue people tend to be terribly boring. But I find that I too am becoming more and more obsessed with a single issue, and I think you should be too. I’m not talking about the coming workers’ revolution, however, but something else: Michigan’s infrastructure.
