As unworkable (and yes, I know that his supporters will insist otherwise) as Yang's basic income proposals were, Yang was the only Democrat that made any effort to show how life would be better under his policies.
You'll also note that that was part of Donald Trump's appeal: the promise of jobs returning from overseas, in particular. His slogan was "Make America Great Again."
You look at the Democratic field... and so much of it is abstract, negative, and worst of all, DIVISIVE. Their longstanding gambit of identity politics and victimhood hustling has created a hodgepodge of policy positions that not only benefit only narrow demographics, but are often divorced from basic truths. Some even demonstrably HURT the very people they claim to help.
