The linked paper is strongly biased towards the ownership class--and the think tank is labeled "libertarian-conservative" on wikipedia, so I'm skeptical of the conclusions.
Yea, almost anyone in the US asking about the productivity implications of unionization will be coming from the ownership class, as US unions don't see that as their problem vs. building worker power.
I couldn't find a paper about US unions increasing productivity. Can you?
Fair. And I didn't look for other papers. If the discussion is simply "unions decrease productivity" however that's defined, that may be true. But by how much? Is that a problem? To whom?
I suspect unionization is better for more people overall.
