How is it possible that this person (and his commenters) and this person live on the same planet?

A definition of economics is “the study of incentives”; an idea that’s pretty well baked into my brain at this point. This means I have a big problem: I have trouble even empathizing with people who don’t think incentives matter. The word “idiot” comes too quickly to my mind.

(BTW, read the second link. He finds it plausible that increasing taxes on rich workers is regressive policy, at least in a small open economy.)
