This rings true, and explains a couple of the key failings of modern American society. Liberals' wholesale embrace of meritocracy combined with their traditional alignment with public unions has manifested in this bizarre fixation with education. Education has become the sole means for achieving traditional liberal goals within the framework of meritocracy. That trend has directly resulted in the college bubble: a society where everybody spends inordinate amounts of money getting an education that for most of them is a waste if time.
More fundamentally, the leadership of the liberal establishment doesn't seem to really believe in the idea of a flat, egalitarian society. Among the liberal elite in San Francisco, D.C., Boston, etc, there is an intense disdain for the folks who form the backbone of the middle class in other industrialized countries: non-college educated blue and white collar workers. In places like Germany, you can get a white collar job and live a middle class life with just 16 years of formal education. In the U.S., even the liberals don't seem to think that is a desirable state of affairs.
