You might also point out that the Amish ride in cars when they need a lift somewhere and also use power tools if needed for work and the job calls for it.
There are all levels of practice...Around here anyway. I dated a former Amish girl...That was interesting.
Many of them work for the "English". Some don't. Some own their own cars (And they all justify it differently). And some can only drive vehicles owned by their bosses. Some own tractors but only ones without rubber on the wheels. Some put lights on their buggys, some don't...etc, etc....
Pretty interesting group of people.
