Middle Class Classlessness

I wonder if the general lack of knowledge, culture and familiarity with the fine points of English could be partially attributable to the fact that, after all, we are still one of the nations with the largest middle class, speaking in socio-economic terms. In other countries that still retain clear divisions between the upper and lower classes marked by huge disparities in resources of all types, no one expects the lowly masses to know anything. Despite recent ecomomic hard times, the USA still offers the best shot at improving one's financial circumstances. Education and culture don't necessarily track that improvement, though. Of course, this doesn't explain moronic college students, but as they say, "Garbage in, garbage out."
