I worked at that facility up until last year. It's one of the oldest Amazon buildings around.

Half my family is from right there. Amazon and Walmart. The modern day fruit of the loom factory.

Did they have hookups? Water/electricity.

Yes, the sites are full hookup.

Strange new forms of company towns.

Seems better if you don't want people planting roots, building infrastructure, and getting a local government/police/fire force in place. Amazon can shut the place down and won't have tons of people trapped in a dying town.

Unless of course there is crime, or a fire.

That said, I believe geographic mobility is important and probably one of the things that makes things most challenging as an adult.
