The idea has been refuted by others over a period of several decades.

At this point, it is more interesting that one political worldview still seems quite attached to the idea than the idea itself, which has been clearly shown to be false.

It's quite analogous to trickle-down theory aka the laffer curve. Shown to be false multiple times over the last few decades. Still promoted by people of one particular political worldview and not others.

That's the story here. The idea has been refuted, why are people still talking about it?
