The Threshing Day

The reason that we have such a difficulty in saying yes to life, no contraception, is at least in large part because we are living in a world in which children are not useful to the farm. And men, many hands do not make light work. They're just there and you have to entertain them for 18 years. So it seems to me like the way you're describing the threshing day is that the rather the problem of the efficiency analysis is that it always begins from some premise of what work is being done.
