[Guest post by Stephen Wunker] Congressional Republicans keep insisting that deep cuts to government spending will help boost growth, and create jobs, in the short term. But that claim doesn’t make a lot of sense. Most economists think that federal spending on public works and aid to the states kept the recession from being much worse. What about the future? You wouldn’t know it from the Republican leadership, or their many cheerleaders in the press, but government spending can help bolster the economy in the long term as well.
