With respect to the first conclusion, The Armchair Economist warns that fixing your fiscal problems by increasing taxes is like paying off your credit card bills by going to the ATM more often, and is not a recipe for success.
And as far as the second goes, holding on to this vision of a high-service utopia is at best foolish and at worst dangerous. It's as if these folks have never heard of the Soviet Union, or read Brave New World, or recognized the fact that Western Europe's combination of high-immigration and low birth rate is a path to extinction.
Quite apart from these criticisms though, is the question of whether or not we really are a low-tax state.
Economist Greg Mankiw offers an alternatvie persepctive of our tax burden by taking a look at taxes per person, rather than as a percentage of GDP. He finds that on this basis the U.S. falls between.........Canada and the U.K. Not exactly tax-haven territory. He notes:
The bottom line: The United States is indeed a low-tax country as judged by taxes as a percentage of GDP, but as judged by taxes per person, the United States is in the middle of the pack.So maybe our tax burden isn't really light enough to fully transform the United States into a government catered paradise, even if such a thing were possible.
Yglesias offers a criticism, but he loves the idea of a high tax/high service state, and thinks it's a real possibility.
