Yeah, I'll definitely grant that both parties are in the pockets of billionaires, although one seems to more than the other. There's a reason so many of them flock to one side.

The only explanation I can think of for the constituency is that people like a confident but far-fetched proposal more than an undramatic but feasible one. Slowly chipping away economic inequality and strengthening labor protections and introducing social benefits actually works, it just doesn't sound as impressive as "I will quickly and singlehandedly fix the cost of living (source: trust me)."
