We're learning that in the debates over public education funding. For some reason, at least in the US, public education is justified if and only if it creates a more productive workforce. Why the government should subsidize the cost of training employees is rarely stated (probably for a good reason).
Well, of course. People aren’t educated for happiness, or even to be better humans. They are educated to standards that meet the expectations of the work place, since nearly all members of society will live to sell themselves for wages (unless they join the ranks of capitalists).
Capital requires an always-ready labor pool whose numbers exceed available employment. It helps keep constant downward pressure on wages. It also ensures people who aren’t hired—or are fired—are available the next time capital needs to put them to work to create more capital.
Mass education can’t be effectively sold to the People as the thing that enables them to become a wage slave. However, capital has long convinced the state to take an interest in economic growth at nearly all costs, so the state doesn’t even question the ways in which it is employed by capital to secure new markets, more labor, and more capital.
That said, it obviously isn’t education that creates a more productive workforce alone—but it makes for an effective bludgeon with which certain interests can beat back efforts to teach things that aren’t considered to be job-relevant. Education merely produces the raw human material capital can put to work to create more capital, without having to shoulder the cost/time burden itself. The extent to which capital successfully externalizes costs onto society at large is quite impressive.
