The bearded gentlemen smiled at me and said the key is the word "own". The tools belonged to the subcontractor who hired them. They were just using them to do the job.
He even gave me a catalog of tools they could own-- everything from kitchen gadgets to mechanical tools. None required electricity, power or batteries of any type. I bought a few to use in my garage if everything collapses. I think the Amish will suffer a lot less than most of us in such an event.
When I said Amish made a moderately good living I meant it. But I consider lower middle class a moderately good living. Maybe that’s because I spent a good part of my life extremely poor. We all have different perspectives.
