FDR began the entitlement era with the New Deal and Social Security, but for decades it remained relatively limited. Spending fell dramatically after the end of World War II and the U.S. debt burden fell rapidly from 100% of GDP. That changed in the mid-1960s with LBJ's Great Society and the dawn of the health-care state. Medicare and Medicaid were launched in 1965 with fairy tale estimates of future costs.

Medicare, the program for the elderly, was supposed to cost $12 billion by 1990 but instead spent $110 billion. The costs of Medicaid, the program for the poor, have exploded as politicians like California Democrat Henry Waxman expanded eligibility and coverage. In inflation-adjusted dollars, Medicaid cost $4 billion in 1966, $41 billion in 1986 and $243 billion last year. Rather than bending the cost curve down, the government as third-party payer led to a medical price spiral.

LBJ launched other welfare programs—public housing, food stamps and many more—that have also grown over time. Last year, the panoply of welfare programs spent about $20,000 for every man, woman and child in poverty, according to Robert Rector of the Heritage Foundation.

Social Security's fiscal trouble began in earnest in 1972 with bills that increased benefits immediately by 20%, added an annual cost of living adjustment, and created a benefit escalator requiring payments to rise with wages, not inflation. This and other tweaks by Democrat Wilbur Mills added trillions of dollars to the program's unfunded liabilities. Believe it or not, these 1972 amendments were added to a debt-ceiling bill.
