'[A plan] has to include progressive taxation. It has to include increases in wages and benefits. It has to include the willingness to tax the wealthy so we can invest infrastructure, so we can invest in education again,' de Blasio told NBC. 'That's what I think progressives and everyday Americans will be looking for from Hillary and all other candidate.' De Blasio said that  Clinton's work that proved to be successful during her 2000 Senate run would be repeated in 2016 - highlighting her previous efforts to effectively listen to what was happening to everyday people . He said that going into this year as a candidate, Clinton has a 'tremendous opportunity' to present a progressive vision as a result of how different circumstances are compared to when she ran in 2008 - with the economic crisis that impacted so many Americans. De Blasio also noted that a lot of the work that proved to be successful from her 2000 Senate bid would be repeated this year, citing her efforts to listen to what was happening to everyday people. 'I think that's going to be more necessary this year than ever before, because people in this country are hurting,' said de Blasio. 'The Great Recession set people back on their heels in a way we have not seen in decades and decades. 'I think it's important for Hillary to hear those stories of the American people. I think it will make her a stronger candidate.'
