Could one of the factors for the Amish be teamwork? Tradesmen are often competing with their peers and working very fast, sometimes too fast and at risk of injury. All of the documentaries I have seen watching the Amish work, they work as a team following the mantra slow and steady wins the race. They work hard, but as a group.
