I saw a post or a comment earlier about a guy trying to do something like a labor commune, where people help each other out improving their farms or working them or whatever.
He didn't find much success, and he was trying to understand why.
The bottom line is TRUST. If you provide labor to your neighbor, you have to trust that he will do the same. If he doesn't, then trust is broken.
How do you get trust? You have to develop friendship, kinship, etc... Eat a meal together. Get to know each other. As an engineer / scientist type, I understand WHY salespeople spend all their time being friendly to their customers. They rely on TRUST.
I highly recommend going to a church to find people who could be trustworthy. It will take years to develop that trust between people and families. Once you get it -- it's a gold mine.
Now, what do you do for those years? you volunteer and freely give of yourself and your substance to your neighbors. Do the sort of thing Jesus told us to do.
If they don't reciprocate, then stop sharing with them.
People used to think that bartering was the original way people traded with each other, and then barter evolved into money. This is simply not true. It all started with people giving each other gifts, expecting nothing in return. Over time, people start asking for specific gifts, and then they respond with asking for certain kinds of gifts. People weren't trading, they were giving gifts to each other.
This is what diversity stole from us. They don't trust us, it doesn't matter whether we trust them. If they don't reciprocate, they must be excommunicated from the village.
The history has been mostly wiped out and today everyone is taught the US was founded on individualism, which is just untrue, it was always community based up until post WW2.
The Amish are a tight knit community just like you describe.
