@hamishb "Underdeveloped" means what it says: people were poor, they had little access to good education and work and leisure opportunities, health outcomes were bad, precious few services and amenities were available, etc. You're imagining a rose-tinted version of the past that never existed.
Have you ever actually lived in the countryside?
@hughster Old towns all over where I live in Ontario have centres full of solid commercial building and fine houses. They were quite prosperous. There were regional train services and milk-run buses regularly.
