On Monday's broadcast of CNBC's "Last Call," Professor of the Practice of Economic Policy at Harvard University and the Harvard Kennedy School Jason Furman, who served as Chairman of the Council of Economic Advisers under President Barack Obama and on the Council of Economic Advisers and the National Economic Council under President Bill Clinton dismissed arguments that corporate greed is the cause of inflation and argued that companies always try to maximize their profits and didn't just start deciding to do so in the past couple years, and the real culprit was demand spiking.
