Peter Diamond, the Nobel Prize-winning...

...economist (whom Senator Richard Shelby thinks is unqualified for the Federal Reserve), says the United States should be spending more on infrastructure (my emphasis):

Infrastructure spending is not a vehicle for dealing with a normal recession. But once you recognize this recovery will be slow, you realize this is a time when we should be doing major spending on infrastructure. And a lot of the infrastructure investments are stuff we’re going to have to deal with eventually, so doing it now doesn’t actually add to the trend debt problem, and doing it now means we’re doing it with otherwise unused resources, both in terms of labor and capital, so that makes it cheaper for the economy.
