From David Brooks's Marx Apparition:

"The educated class has torn away from the family its sentimental veil and reduced it to a mere factory for the production of little meritocrats. Members of the educated elites are more and more likely to marry each other, which the experts call assortative mating, but which is really a ceaseless effort to refortify class solidarity and magnify social isolation. Children are turned into workaholic knowledge workers - trained, tutored, tested and prepped to strengthen class dominance."
