Yeah, and one of the big things about Amish communities is while they aren’t necessarily cash rich because their raw income usually isn’t that high, they are “net worth” rich. Amish farmers are much more likely to own their property outright, with no outstanding mortgage. The Amish aren’t opposed to mortgages though, and a typical Amish farm will often be purchased with one, but making that monthly payment is seen as a family responsibility so if something is going bad with one farm that farmer’s brother or parents would kick in money to make sure the mortgage is paid before they let the payment lapse–not paying debts is seen as shameful to the entire extended family.
The Amish are just as likely as other farmers to focus on producing products that make good money, but because of their unique lifestyle they usually dedicate a small portion of their land to basic survival produce so they can generate a lot of their own food. During the Great Depression era most small farmers raised crops that primarily you would sell for cash, they would use the cash to buy groceries and etc, so if the crop market collapsed those farmers were a lot more likely than the Amish to be unable to feed themselves. A typical small farmer back then probably had a few things going to feed themselves (probably had chickens for sure, for example) but not enough to truly live off of with $0 cash income.
