Robert Reich, U.S. Secretary of Labor, from 1992 through 1996, writes:
Let me say this as clearly and forcefully as I can: The federal government should be spending even more than it already is on roads and bridges and schools and parks and everything else we need. It should make up for cutbacks at the state level, and then some. This is the only way to put Americans back to work. We did it during the Depression. It was called the WPA.
Yes, I know. Our government is already deep in debt. But let me tell you something: When one out of six Americans is unemployed or underemployed, this is no time to worry about the debt.
