Wife and I are still pretty simple even with modern luxuries. We stay at home with no close neighbors on 20 acres surrounded by national forest on three sides.
Go into town maybe twice a week for groceries. We're pretty much loners when it comes down to it. Our 3 dogs are our family, we love them like children actually.
May sound pathetic but we are happy, especially now that we no longer live off-grid and have real plumbing and electricity.
The Amish can have the no indoor plumbing and no electricity. May be a simple life but there is a reason most don't embrace it. It is 200 years ago. Could also go back to the ancient Roman way of living. They were actually pretty advanced for the time. (Plumbing)
I respect them living the way they want, just not the way I, or my wife, want to live in modern days. Feel lucky we were born in modern times with modern conveniences.
