The big programs are well-known. In 2011, Social Security had 49.6 million recipients and Medicare 45.6 million, most of them overlapping. There were 5.2 million Americans with unemployment compensation and 3.2 million with veterans’ benefits. An estimated 107.2 million people received “means-tested” benefits available to those with low incomes. Medicaid had 80.5 million beneficiaries, food stamps 48.3 million and WIC (Women, Infants, and Children) 23.1 million. Among households with means-tested benefits, almost a third received three or more.

President Obama hasn’t controlled this spending or opened a debate about which benefits might — in the national interest — be curbed. His reluctance reflects conventional wisdom that questioning benefits is a political loser because it arouses the fears of millions of potential voters. But Obama’s expediency leaves Romney an opening, albeit a high-risk one. He could seize the moral high ground by posing the hard questions necessary for a future that does not penalize economic growth or overburden today’s young with taxes or debt.

This is an opportunity that Romney seems unwilling or unable to take, his brief engagement with Medicare aside. After the video’s release, he might have apologized for his clumsy language, while still urging voters to find a better balance between America’s past promises and future prospects. But he seems to lack the rhetorical skills to convince people why a rigid defense of the welfare state — effectively, Obama’s position — threatens the welfare of today’s young and tomorrow’s children.
