Most of those business are Amish owned and run. Guy I knew had three or four giant pickup trucks, generally he was towing pigs to slaughter but he would cart anything they asked him to. They didn't trust the English to handle their business as far as they could throw them.

It's worth pointing out that the guy with the cell phone and pickup trucks also believed the world was flat. He was not a flat earther the way we think of one, and wouldn't know what that meant if you asked him. It just happens to say in the Bible that the world has 4 corners, and so it must. As, according to him and almost every person in Amish communities everywhere, the Bible is literally and 100% truth.
