If small, rugged farms have not filled the countryside, what has? … For the past century, rural spaces have been preferred destinations for military bases, discount retail chains, extractive industries, manufacturing plants, and real-estate developments.

Yup, about right. The small town I live in depends economically upon a Navy installation, a GM plant, a cement plant, and Indiana University. The Ford/Visteon plant closed in 2007, and its space was filled with defense contractors. There are seven Dollar Generals within a ten minute drive.
