Decoupling of wages from productivity
The decoupling of median wages from productivity, sometimes known as the great decoupling, is the gap between the growth rate of median income and the growth rate of GDP per person or productivity. Erik Brynjolfsson and Andrew McAfee highlighted this problem toward the end of the twentieth century and the beginning of the twenty-first century.
