In 2019, DeLong said that he and other neoliberals had been “certainly wrong, 100 percent, on the politics” of economic policies. While he continued to believe that “good incremental policies” might be superior, he concluded that they were unattainable politically, because of the absence of Republicans willing to work toward such goals. Instead, DeLong said, he favored "Medicare-for-all, funded by a carbon tax, with a whole bunch of ] rebates for the poor and public investment in green technologies." He concluded, "The world appears to be more like what lefties thought it was than what I thought it was for the last 10 or 15 years."
