On Thursday's "CNN Newsroom," 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 argued that to decrease oil prices, "you need to make it easier and more predictable for oil companies, oil refiners to build capacity in this country." And that the profits tax proposed by Democrats won't do that and could make the problem worse.
