It think it was the general tone of “the filthy rich got that way off the backs of the working class” and “without the heroes of the working class, we would be screwed” in the post that qualifies it as Socialism 101.
No, I didn't read it that way, but as more of a call for respect for the people who do their jobs the way they're supposed to and really move the work out there, but don't have the big ideas, the high-toned educations (and that includes parental education, which is underweighted), the conceptual framework to make such a large contribution to society as inventing a new product or service that everyone can use, or founding a company, or creating a great new arbitrage play.
