Famous quotes containing the word class:

    “Indeed, there are no easy correlations between parental ideology, class or race and “successful” child development. Many children the world over have revealed a kind of toughness and plasticity that make the determined efforts of some parents to spare their children the slightest pain seem ironic.”
    —Robert Coles (20th century)
