The poorest people in the Midwest can be seen walking down the sides of busy highways that have no sidewalks, carrying large loads of groceries for miles at a time.
You're just echoing my point. This city centric view that "cars aren't needed", "cars are a failure" is not helpful. The Midwest and South do not have the density to support those statements, moreover, most folks end up having to budget for a car first, then a home because of this.
Making cars easier to afford and maintain would benefit the South and Midwest a lot more.
