Lovely little civilization we have, eh?
edit: Huh, must be nice to live in places where that apparently doesn't happen? It's been a comically recurring theme in nearly every city I've lived in - potholes weren't just potholes, they were favors and tools and penalties and grifts. If you've never seen this happen, I'd recommend digging a bit deeper. Very few places have their collective shit together sufficiently to handle the relatively small problems like potholes very well. If your community does, then kudos!
Also, union labor is not mandatory for public work, but the prevailing wage scales that contractors are required to pay their workers do line up pretty closely to the actual union wages. It’s a good thing that people get paid a living wage, in my opinion. There are a lot of facilities that require union labor for certain trades due to the risk involved: mechanical, electrical, and plumbing for the most part.
