Trump’s Delusions of Competence

Last fall, the now-presumed Republican nominee declared: “Our wages are too high. We have to compete with other countries.” Then, as has happened often in this campaign, Mr. Trump denied that he had said what he had, in fact, said — straight talker, my toupee. But never mind.

.. The truth is that wage cuts are the last thing America needs right now: We sell most of what we produce to ourselves, and wage cuts would hurt domestic sales by reducing purchasing power and increasing the burden of private-sector debt. Lower wages probably wouldn’t even help the fraction of the U.S. economy that competes internationally, since they would normally lead to a stronger dollar, negating any competitive advantage.

The point, however, is that these feedback effects from wage cuts aren’t the sort of things even very smart business leaders need to take into account to run their companies. Businesses sell stuff to other people; they don’t need to worry about the effect of their cost-cutting measures on demand for their products. Managing national economic policy, on the other hand, is all about the feedback.
