Some of my more thoughtful conservative friends have criticized President Obama's bigger initiatives -- like the health reform law -- from a "first principles" argument that economic liberty is the foundation of, well, liberty liberty. Any governmental act that interferes with the rights of individuals to their property or profit is a reduction of liberty and thus potentially a step down the slippery slope to tyranny. I think it's an insightful argument, but I also think it's got limits.
And I think those limits might be demonstrated by the Heritage Foundation's 2010 Index of Economic Freedom. What's notable is that the two "countries" ranked highest on the index -- Hong Kong and Singapore -- might be great places to make cash, but they're not what most Americans would think of as substantially "free." (The United States ranks ninth.) Hong Kong might be listed as a separate "country" for the purposes of the index, but it's ruled by Chinese Communists; it might be more free than the mainland, but there are still rather significant concerns about freedom of expression. And Singapore? It's the authoritarian government that gave us caning and ranks 133rd in the World Press Freedom Index.
Heritage's index, obviously, doesn't take those things into account. Instead it ranks each country on a list of 10 criteria, including property rights, business freedom, government spending and "labor freedom." Weirdly, Canada -- with its big socialistic health care system -- ranks ahead of the United States.
I don't think my thoughtful conservative friends would assert that countries with libertarian policies only for corporations and not for citizens are truly free. Nor would I want to suggest that the ability to express yourself freely is the only criterion for liberty; economic liberty is an important component. But it appears that low taxes and free trade are no guarantee of freedom; I suspect it probably follows that a more-regulated health system isn't the end of our Republic.
