From the Center for Freedom and Prosperity: “Government spending can promote economic growth if money is used for core “public goods” such as rule of law and property rights. But the burden of government spending in the United States and other industrialized nations is far higher than needed to finance such activities. Citing scholarly studies, this CF&P Foundation video examines the Rahn Curve, which graphically illustrates the negative impact of excessive government spending. http://www.freedomandprosperity.org.”

This is a great video, George. Thanks for sharing it.
One wonders if this applies to “government” in general, such as church government.
For instance, might the United Methodists have outgrown the Southern Baptists during the 19th and early 20th centuries had they not overshot the level of control on the Rahn Curve?
