He doesn't otherwise come off as a lazy writer, he can't really pass for "folksy"

It seems to be the titles of his posts and not the content which he likes to keep extremely simple, even trite. I take it as wry counter signalling. There is a touch of ironic contrast between what could superficially look like a naive opinion and reasoning that is in fact based in some measure on sound economic principles, or at least of premises that the intended audience would accept.
