For example, think about how many times you've seen people say they don't care about gas prices because they don't have a car: they take public transportation (which uses gas..) or walk.
The supply chain consists of things magically appearing in bodegas for their consumption, and that's why their pejoratively-named "flyover country" is and does nothing, they think.
Perhaps that's true in your experience, but I hear this fairly regularly including various subreddits, Twitter, and I've heard it here on HN as well (it's been a while, I don't care to dig through my comment history for links to the specific threads). Specifically, the argument takes one of two forms: either we should extend public transit and cycling infrastructure everywhere (including rural areas) or that we should implement policies that expressly accelerate urbanization and penalize rural life (or a combination).
