But this conservative vision of social insurance is wrong. It’s incorrect as a matter of history; it ignores the complex interaction between public and private social insurance that has always existed in the United States. It completely misses why the old system collapsed and why a new one was put in its place. It fails to understand how the Great Recession displayed the welfare state at its most necessary and that a voluntary system would have failed under the same circumstances. Most importantly, it points us in the wrong direction. The last 30 years have seen effort after effort to try and push the policy agenda away from the state’s capabilities and toward private mechanisms for mitigating the risks we face in the world. This effort is exhausted, and future endeavors will require a greater, not lesser, role for the public.

Beyond the need to deflate the imaginary landscape of the contemporary right, there’s also a need for liberals to reform their project. Liberals need to reclaim the public. Liberals need to be able to articulate that the welfare state succeeded in exactly the ways that the private insurance system failed in the Great Depression. Patchy and spotty as it is, today’s welfare state backstopped the economy during the Great Recession, and is still capable of providing broad security for the American people.

It also requires liberals to argue for their own definition of charity, based on the equality that can thrive when the public manages the risks we face, rather than the inequality that’s bred by a private form of dependency. As President Truman said in a 1946 radio address to kick off the annual fundraising campaign of the Community Chest, the predecessor to today’s United Way:

I like the campaign slogan this year: Everybody Gives, Everybody Benefits. It marks a significant change in our thinking about the word “charity.” Today our contributions to the Community Chest are not alms given by the wealthy few to the poor. This Government, through its public welfare program, has long since accepted its responsibility to see that no citizen need face hunger, unemployment, or a destitute old age. The word “charity” has regained its old, true meaning—that of good will toward one’s fellowman; of brotherhood, of mutual help, of love.

The state does many things, but this essay will focus specifically on its role in providing social insurance against the risks we face. Specifically, we’ll look at what the progressive economist and actuary I.M. Rubinow described in 1934 as the Four Horsemen of the Apocalypse: “accident, illness, old age, loss of a job. These are the four horsemen that ride roughshod over lives and fortunes of millions of wage workers of every modern industrial community.” These were the same evils that Truman singled out in his speech. And these are the ills that Social Security, Medicare, Medicaid, food assistance, and our other public systems of social insurance set out to combat in the New Deal and Great Society.

Over the past 30 years the public role in social insurance has taken a backseat to the idea that private institutions will expand to cover these risks. Yet our current system of workplace private insurance is rapidly falling apart. In its wake, we’ll need to make a choice between an expanded role for the state or a fantasy of voluntary protection instead. We need to understand why this voluntary system didn’t work in the first place to make the case for the state’s role in fighting the Four Horsemen.
