Beautiful! Educate the poor for "viable routes to mobility" considering their low social economic status. We already have a defacto two tier educational system -- one for the well off and one for those who wait on them (and a diminishing middle class of waiters striving to become more waited upon).
This article shows that those groups within our capitalist society that do poorly academically do so because society has stacked the chips against them and they know it. The social "science" solution of the bourgeoisie is not to get rid of capitalism but to modify "the educational environment" to make the poor better satisfied with their role at the bottom of the heap. Betsy DeVos is doing her job.
