Right, it is quite a stretch, I get it. Citizens pay taxes and vote thereby have extremely diluted control over the means of production for schools, as opposed to private schools where they control it by means of their dollars going towards whichever one they choose (causing them to compete for that privilege). It's an extremely watered-down form of socialism existing inside of an other capitalist-dominated society, but the main point is that whatever it is / whatever words are used to describe it, the goal of it runs counter to the goal of capitalism to make profits, and instead just benefits the populace directly (many caveats aside, like how schools are funded in large measure from local taxation, causing a segregation effect where the rich tend to congregate together and thus have good schools whereby the poor must also congregate together, out of whatever is leftover, and thereby have lesser quality schooling - but that aside, within a given school district, the aim is usually for the children to be taught equally without regard for ability to pay, though heavy caveats exist there too e.g. supplies, lunches, etc.).

Anyway, I cannot defend the OP meme, I was only trying to point out what looks to have been the POV behind it.
