I disagree. I'm not saying that they are exactly the same, of course not. But imo my DH's agrarian community has infinitely more in common with pre-industrial societies than it does with modern British society.
They are completely self sufficient subsistence farmers, use traditional technologies and traditional farming methods. No access to modern technology, no "jobs", no modern medical care etc. Live in extended family units as they have done for centuries, people and animals all under one roof. DH is one of only two people from his and surrounding villages to have left, and the only one overseas.
Yes, of course there will be ways in which this community, like any other, is touched by modernity. But actually very little, and I would say definitely not enough to have touched on the basic fabric of family life. In DH's community, life is all about survival still. Men work, women work and yes, the kids do all work in the fields and help with tending the animals. And the very young are left with whoever happens to be around to take care of them, whether that happens to be a neighbour, grandparent, sibling or whatever. The notion of "quality time" would be a mystery to these people, and our lives - whether WOHM or SAHM - are unimaginably far removed.
