Sooner or later, there will be a giant battle in Washington over the value-added tax. The people who want bigger government (and the people who are willing to surrender to big government) understand that a new source of tax revenue is needed to turn the United States into a European-style social welfare state. But that’s exactly why the VAT is a terrible idea.

I explain why in a column for Reuters. The entire thing is worth reading, but here’s an excerpt of some key points.

Many Washington insiders are claiming that America needs a value-added tax (VAT) to get rid of red ink. …And President Obama says that a VAT is “something that has worked for other countries.” Every single one of these assertions is demonstrably false. …One of the many problems with a VAT is that it is a hidden levy. …VATs are imposed at each stage of the production process and thus get embedded in the price of goods. And because the VAT is hidden from consumers, politicians find they are an easy source of new revenue – which is one reason why the average VAT rate in Europe is now more than 20 percent! …Western European nations first began imposing VATs about 40 years ago, and the result has been bigger government, permanent deficits and more debt. According to the Economist Intelligence Unit, public debt is equal to 74 percent of GDP in Western Europe, compared to 64 percent of GDP in the United States (and the gap was much bigger before the Bush-Obama spending spree doubled America’s debt burden). The most important comparison is not debt, but rather the burden of government spending. …you don’t cure an alcoholic by giving him keys to a liquor store, you don’t promote fiscal responsibility by giving government a new source of revenue. …To be sure, we would have a better tax system if proponents got rid of the income tax and replaced it with a VAT. But that’s not what’s being discussed. At best, some proponents claim we could reduce other taxes in exchange for a VAT. Once again, though, the evidence from Europe shows this is a naive hope. The tax burden on personal and corporate income is much higher today than it was in the pre-VAT era. …When President Obama said the VAT is “something that has worked for other countries,” he should have specified that the tax is good for the politicians of those nations, but not for the people. The political elite got more money that they use to buy votes, and they got a new tax code, enabling them to auction off loopholes to special interest groups.
