Not taking away anything from the Amish, or anyone else for that matter, but it seems to me that the point here is-

All of us have attitudes, behaviors, and beliefs that effect the risks in our lives- some subtly, others greatly. Some amount risk is unavoidable, some risk is acceptable, and sometimes risk is desired. Cost vs. benefit often is a deciding factor in determining what risks are to be mitigated. And in many cases the most obviously dangerous situations are the best protected, while the seemingly mundane ones prove to be the most dangerous, typically through complacency. The truth is that most safety systems are not entirely passive- the user needs to be involved in their own safety.
Also, this tragedy illustrates the huge difference between static and dynamic systems. Something, like a tractor, might be able to sit on a very steep slope and not fall over. But the same thing in motion can be be upset by relatively small factors.
My heart goes out to the family, and especially the children.
