Politics is parasitic. Even at its best, it produces no goods of its own; it has only that which it takes from what others produce. For about 200,000 years, human beings produced almost nothing — the per capita economic-output curve is nearly flat from the appearance of the first homo sap. until the appearance of JethroTull and Eli Whitney. We’ve had politicians since before Hammurabi, but we didn’t escape the shadow of famine until a few thousand years later when somebody discovered that the wars fought over dividing up the harvest could be prevented by making that harvest bigger — and then figuring out how to get that done. Politics is a footnote — the inventory in your local Walmart is the headline.
