Having grown up in a rural place, I’d say the way infrastructure is built in America arguably serves the rural poor the worst. Totally dependent on cars to go anywhere, with effectively no choice but to spend a large portion of your income on a likely old and and unreliable vehicle, to get to a job that will happily fire you for being late if you have a problem with it. Once upon a time even quite small rural towns had actual shops, trains, even trams, that people could live nearby to, but we’ve mostly gotten rid of those.
