Those who said after President Barack Obama’s speech last week to Congress that government does not create wealth, does not create jobs and cannot stimulate the economy spoke nonsense. So do those who say that only private business creates wealth, as if any revenue going to taxes destroys wealth. Adam Smith, who figured out market capitalism in his 1776 book “The Wealth of Nations,” could set them straight. We have plenty of equally competent economists who understand these issues today. They just do not get the attention that the news media lavish on high-profile politicians and pundits who speak with absolute certainty on matters about which their words show they know nothing.
