I can vouch for that, having been born and grown up on a couple of very isolated and lowtech subsistence farms, and having joined in the endless work as soon as I possibly could do so with competence and safety. You worked because everybody did. Between work I was homeschooled, with the advantage of an extensive, multilingual and wide-spanning home library and older relatives who believed passionately in the virtues of education. I know that a lot of such arrangements nowadays tend to isolate and exploit the kids, usually because of some odd religious or political bias, but we were just living way out. The end of this was that I grew up knowing both how to work hard and pay attention and how to study in the times when I could. Plus my older brother and I had fun.
And when we came to live nearer to regular schools, I both already knew how to work and had a good enough education that I was able to get through the rest of my secondary education and university, which we could never otherwise have afforded, on Commonwealth scholarships, which were competitive academic scholarships. Working from a young age doesn’t hurt, and providing that the rest of life is balanced, may very well help. When my own children were small we lived in the backbeyond of Far North Queensland, and they also were homeschooled and worked with the adults until we had to move nearer to a city for medical reasons. They turned out okay.
