The Power of the Glave
I agree. Sometimes "learning from the past", it's possible to learn the wrong lessons.You said it better than I could have peter, it's certainly a different world, back before WWI the majority worked on farms, now, well you said it all.
The problem today is that there has been a seismic shift in what is "morally acceptable", in society. A shift for the worse. As has been well pointed-out by both you and Petergunn.
And it's the same in "rural" culture, as it has changed in the cities.
I am a farmer in Nebraska. On the same farm my late parents lived on since 1936. Dad and Mom often talked about the Depression years of the 30's. When people---literally---were starving and destitute. However even in that situation, there was little to no rampant crime such as theft and assaults, in rural society. Because that was a "moral line" that very few would instinctively cross. At least as far as farms and rural areas back then.
So having your "own farm out in the country, all safe and well-stocked", will NOT automatically be the secure and safe place so many posters here seem to assume. Instead, it will be regarded as a Fort Knox of food and shelter. And the big threat will NOT be from "thugs from the city coming out to rob and rape". It will come from your neighbors down the road.
