There is a grain of truth in that rural areas get worse government service. Power outages last for longer, often they don't even have sewer hookups and have to maintain septic systems, roads are maintained at a lower level, etc. They really do get less benefit (in outcome terms) than city folk.
I think @Greddan@feddit.org hit on the information environment as the reason they can't see that that lower service level comes at a way, way higher monetary cost. Our information aggregators are in the business of making money from engagement, and telling people things they want to hear that sound true is the most effective engagement tool. I don't see the problem getting any better unless we figure out a better information model.
