The greatest problem facing our country is the breaking down into two classes, those who have and those who have not. The growing differences between the incomes of the skilled and the less skilled, the educated and the uneducated, pose a very real danger. If that widening rift continues, we’re going to be in terrible trouble. The idea of having a class of people who never communicate with their neighbors – those very neighbors who assume the responsibility for providing their basic needs – is extremely unpleasant and discouraging. And it cannot last. We’ll have a civil war. We really cannot remain a democratic, open society that is divided into two classes. In the long run, that’s the greatest single danger. And the only way I see to resolve that problem is to improve the quality of education.
