I'm trolling Elizabeth Breunig. Because she said that "Human capital is one of the more odious terms in the capitalist lexicon". And I like the term "human capital", because I think it helps us think more clearly about investment in training and education.
Are new-born babies "human capital"? My first thought was that they possess no human capital, because they haven't invested in learning anything yet, so it was an abuse of the concept to say that babies are human capital.
Then I remembered "Lark Rise to Candleford", (HT Frances), a memoir of 19th century girlhood in a poor English village. Only one couple in the village had any savings. They were saving for their pension. They were the only childless couple in the village. All the other couples had children, who were costly to feed and clothe, but would support them when they were too old and sick to work. Their children were their pension plans.
