Last month, left-wing economist Joseph Stiglitz warned that the term “democratic socialism” poses too great an electoral risk to justify its embrace. He urged leaders like Bernie Sanders and Alexandria Ocasio-Cortez to adopt softer vocabulary instead, suggesting that “progressive capitalism” might do the trick.

While Elizabeth Warren prefers the Stiglitz approach, naming a recent piece of progressive legislation the Accountable Capitalism Act, Bernie Sanders isn’t content to project the message that capitalism can deliver the transformative change that working people need and deserve. Instead, he’s doubling down on democratic socialism. On Wednesday afternoon, Sanders gave a speech seeking to define the term for a new era. “Economic rights are human rights,” he said. “This is what I mean by democratic socialism.”

Sanders defined basic economic rights as “the right to quality health care, the right to as much education as one needs to succeed in our society, the right to a good job that pays a living wage, the right to affordable housing, the right to a secure retirement, and the right to live in a clean environment.” He called these demands a “Twenty-First-Century Economic Bill of Rights.”
