“The trend of increasing service costs defined many of our economic debates for a decade. The popular narrative that college is getting less and less affordable is wrong…These changing trends don’t mean that services are cheap and we can stop thinking about service costs. First of all, there are still some services that are getting less affordable over time — most notably, child care. So there’s still probably scope to bring down the costs of health care and college. But with all that said, the change in the trends in service costs and service productivity mean that our debates about these topics need to change.”From Noahpinion.
