Vice President Joe Biden issued a fiery call for a more equitable tax system as he marched with union workers Monday, diagnosing fairer taxes as a solution to a growing disparity between the wealthy and middle class.<br />"I hope everybody in America has a chance to become a millionaire.<br />And we need some billionaires," Biden said at a Labor Day gathering in Pittsburgh.<br />"But let me tell you something, man.<br />The tax code's not fair.<br />It's simply not fair."<br />Biden's every public utterance is being heavily scrutinized of late amid questions of if, and when, he might enter the 2016 presidential race.<br />"Run, Joe, run," some in the crowd shouted as Biden marched with Steelworkers union members in the Labor Day parade.<br />So far, however, he's offering no new clues on whether he'll get into the race.<br />"You gotta talk to my wife about that.<br />I gotta talk to my wife about that," he said in response to one man's shout that he should run.
