Will the tax cut destroy America's prosperity? Probably not. As Adam Smith observed, there's a deal of ruin in a nation. We have a huge, resilient economy that can survive and recover from even quite bad government policies.
Yet while the tax cut may not be a matter of economic life or death, it is a very serious issue. For one thing, like it or not, the tax cut has become the central political issue in the United States right now. Conservatives who want to reshape America view passage of a large tax cut as a first step toward realizing their vision. For that reason, those who do not share this vision feel, rightly, that they must oppose the plan.
