One basic trend: the increasing importance of investment in children’s education, particularly at the top of the human capital distribution. As a result, the structure of household production has drastically changed

‘Traditional’ patterns (chores and specialization) less important (‘engines of liberation’, Greenwood et al 2005) Human capital production more and more crucial, particularly at the top of the distribution
