I've personally known people who grew up in small Central American or South Asian villages, went to university, worked in a city or even overseas for some years before moving back home, speak 3 or more languages, and are some of the most worldly, broad-minded, and well-educated people I've ever met. All without ever owning or regularly driving a car.
Obviously there are many rural places where people don't have cars and also happen to be living in grinding poverty, but that's not what I was talking about. There are plenty of people in the world who lead rural lives without cars while also enjoying all the things they need and then some, because their societies are set up to facilitate that. They provide examples of how that's possible, which we in the "first world" should be trying a lot harder to learn from.
