I live in an area very close to what we would call Amish country, and worked in that area for a little while. They are extremely hard works, they get shit done, and they do it well.
The well off Amish in my experience are assholes though and they treat their animals very poorly. They run puppy mills and those things are fucking depressing. In the grocery stores you'll see their carts full of junk food, they're known for their baking and it can be very good but they also buy shit premade snack cakes and LOVE Mountain Dew, just shopping carts full of Mountain Dew. We have some near by bulk food stores that are Amish ran and they often will have delis that have good deals on cold cuts and cheese, a couple of them make sandwiches that are fat for a great price.
I don't know how true it actually is, but I've been told there is a lot of inbreeding.
It also seems that a lot of ex-Amish end up having drug and alcohol addictions.
