This index combines them all into one category named “Fiscal Burden,” a decision influenced by a key insight from Nobel Prize–winning economist Milton Friedman: “The true cost of government to the public is not measured by explicit taxes but by government spending.”
Notably, this index does not claim (nor would Friedman) that taxes do not matter. Indeed, the form taxes take can be deeply harmful to a state’s economic growth and ability to attract investment capital and population. That’s the reason tax policy, not just tax burdens, are measured here. Yet government debt matters too, as government bonded-debt levels are essentially future taxes and claims on yet-to-be-created wealth for the political benefit of voters in the present.
Including debt ensures that the rankings do not advantage a state that cuts taxes without cutting spending. Furthermore, a state that generates the minimum revenues necessary (i.e., a low tax burden) to undertake only the most necessary government functions may do so through a growth-restraining tax code, even if the state never has to issue debt.
So, “Freedom in the 50 States” addresses all of these aspects, grouping compatible measures of fiscal burden into a single category. It includes how much tax revenue is collected, the form those taxes take, how much of that money is spent by the government, how much it competes with private labor markets through government employment, and how much debt the government issues in the form of general obligation bonds. This ranking therefore provides a more complete picture than narrower assessments of the overall claims that a state government places on the private sector, both now and in the future.
