John Judis has all the right intentions. He’s looking at the resurgence of openly democratic socialist currents in the United States with a mix of excitement and trepidation. Excitement, because he knows how desperately the country’s workers need social reforms. Trepidation, because he worries that the new left might fall into the familiar traps of insularity and sectarianism.

But while Judis wants us to change society for the better, his response to the failures of twentieth-century state socialism would lead us into the dead end of twentieth-century social democracy.

In his New Republic essay “The Socialism America Needs Now,” Judis makes a passionate plea for the rebuilding of a social-democratic movement — or what he calls “liberal socialism.” He contends that the welfare state and democratic regulation of a capitalist economy should be the end goal for socialists, as past efforts at top-down nationalization and planning yielded the repressive societies and stagnant economies of the Soviet bloc. In contrast, Judis argues, the Scandinavian states are dynamic capitalist economies that are still far more equitable and humane than the United States.
