... actually, but I found one passage in Jonathan Chait's The fallacy of zero-sum politics fascinating: "In 1964, the federal government spent 18.5 cents of the American economic dollar. In 2005, it spent 20.5 cents. This is not what small-government conservatives would call progress."
Why wouldn't they call it progress? Adjusted for inflation. 18.5 cents in 1964 dollars is $1.15 in today's dollars. A three-cent increase over 42 years is spectacularly low.
Update: Inquirer economics columnist Andy Cassel sends me this link that is pertinent to the discussion: The Price of Government.
