There are several branches of the base faith of Mennonites...the Amish, which has four distinct branches witn themselves... as well as Hutterite. All arose out of the Anabaptist movement in Switzerland, Holland and Germany in the Reformation of the 1500's.
Here in the U.S., the Mennonites, Amish and Hutterites are well represented, but it's only the Old Order Amish that still use horse drawn equipment and shun most modern conveniences.
All of the various groups are communal in nature, meaning the land, buildings and equipment are owned by the group and are governed by overseers.
When a new group starts out of existing group they find land and pay cash of it. All of the start-up costs are cash as well... they have no debt to service, which significantly adds to their bottom line. Costs are tightly controlled by just plain good management.
We have several communes near where I live here in the western U.S. , mostly Hutterites and they farm but mostly raise chickens and turkeys at the commercial level and do very well.
Not unfriendly, but they still speak German and are close knit. We travel to their communeen we buy turkeys and chickens, especially at Thanksgiving time since theirsare a far better quality than in grocery stores.
Hope I've answered your question...
