The growth of entitlement payments over the past half-century has been breathtaking. In 1960, U.S. government transfers to individuals totaled about $24 billion in current dollars, according to the Bureau of Economic Analysis. By 2010 that total was almost 100 times as large. Even after adjusting for inflation and population growth, entitlement transfers to individuals have grown 727% over the past half-century, rising at an average rate of about 4% a year...Read the whole thing.
In 1960, entitlement payments accounted for well under a third of the federal government's total outlays—about the same fraction as in 1940, when the Great Depression was still shaping American life. But over subsequent decades, entitlements as a percentage of total federal spending soared. By 2010 they accounted for just about two-thirds of all federal spending, with all other responsibilities of the federal government making up barely one-third. In a very real sense, entitlements have turned American governance upside-down.
