ERIN BURNETT (HOST): OutFront now, Robert Reich, former U.S. labor secretary under President Clinton and Stephen Moore, informal White House adviser. Steve, Bernie Sanders wants to raise social security taxes and investment taxes. Six and a half percent there, six and a half percent there. This is just the latest proposal from a Democrat. STEPHEN MOORE (INFORMAL WHITE HOUSE ADVISER): It sure is, and you're exactly right Erin, that almost every Democratic presidential candidate is coming out with some new plan to raise taxes even higher on the one who came before them.
