Scott Galloway, a professor at NYU's Stern School of Business, says it's not a question of can Big Tech become too big, but can it become too powerful. Prior to that, Steven Wieting, Citi Private Bank's chief global investment strategist, says monetary policy won't be the driving force changing economic markets if Jay Powell becomes Fed Chair. Rick Mishkin, a professor at Columbia University's Business School, says Jay Powell would do a terrific job as Fed Chairman, but Janet Yellen would still be better. Finally, Austan Goolsbee, former chairman of the U.S. Council of Economic Advisors, says Congress isn't even remotely trying to get a 1986-style "comprehensive" tax reform.
