You really think the only reason they increased their labor costs by billions is because a now irrelevant populist from Vermont doesn't like rich people?
Bernie Sanders is now the Chair of the Senate Budget Committee. He's not irrelevant, that's a position with actual power. His committee is the one from which the current 1.9T stimulus bill originates, for instance. That bill doesn't get passed without going through him first. That's far from irrelevant.
