Perhaps no single aspect of the digital revolution has received more attention than the effect of automaton on jobs, work, employment and incomes. There is at least one very good reason for that — but it is probably not the one most people would cite.

Not everyone welcomed this transition. Many worried that reduced demand for human labor would lead to permanently high unemployment. But that didn’t happen. Instead, rising productivity and incomes bolstered demand, and thus economic activity. Over time, labor markets adapted in terms of skills, and eventually working hours declined, as the income-leisure balance shifted.
