He praised the recent victory of the Democratic Socialist mayor-elect of New York, Zohran Mamdani, who he said was addressing people’s everyday concerns, in contrast to politicians of both the center-left and center-right.
Mamdani, who last week surged to victory after defeating both Democratic rival Andrew Cuomo and Republican contender Curtis Sliwa, ran a strikingly effective media campaign centered on the city’s spiraling cost of living. His platform included promises to provide free bus travel, state-owned supermarkets and rent-controlled apartments.
Stiglitz, who described himself as “very market friendly,” nonetheless said he thought the left-wing mayor had opened up space for debate.
“He’s saying things that are important to people: things like housing, food, transport, health care,” said Stiglitz. “He’s just ticking down the list of things that make for the necessities of a decent life, and he’s saying things aren’t working right.”
Stiglitz won his Nobel Prize in 2001 for work on information asymmetries in markets, and served as a chief economist at the World Bank and as chair of the Council of Economic Advisers during former President Bill Clinton’s administration, where he had a famously rocky relationship with Treasury Secretary Larry Summers. With its embrace of globalization and the Internet revolution, Clinton’s team was hugely influential in drawing the parameters for the modern world economy.
The influential economist said that tackling inequality wasn’t just a moral choice, but a political necessity. He added that the yawning gap between the rich and poor was undermining the U.S. in its economic and technological competition with China.
“[The U.S.] won’t win if we are a divided society, a polarized society,” said Stiglitz, echoing rhetoric of the last Cold War. “The greatest weakness in the U.S. today is this division.”
