What the HELL is wrong with the Amish?

Today, a three year old little boy was killed. He wasn't hit by a car...he didn't sucumb to an illness or anything else you might think that would befall a child of that age. This little guy was killed while riding on a horse-drawn manure spreader with his two year old brother. The poor little tyke somehow fell onto the feed belt of the spreader and was propelled underneath, basically ending up covered by a heavy layer of shit.
This is the second incident of this type, in as many months. The last one was another small child that was sent inside a grinder by his father....who then turned it on before checking to see that the boy was out!
I think that these two horrible deaths are textbook examples of "endangering the welfare of a child".
How many more children must die in gory farm machinery deaths until something is done to stop this?
