intersting hypothesis:

“My own theory about today’s stagnation focuses on growing angst about rapid advances in technologies that could eventually replace many or most of our jobs, possibly fueling massive economic inequality. People might be increasingly reluctant to spend today because they have vague fears about their long-term employability – fears that may not be uppermost in their minds when they answer consumer confidence surveys. If that is the case, they might increasingly need stimulus in the form of low interest rates to keep them spending.”
