From a thoughtful essay by Harvey Mansfield, Our Parties, Part One - The Democrats: how progress became drift:
Now that we have considered difficulties in the idea of progress, it is time to enter the politics of progress. Progress reduces the scope of politics and thus minimizes the relevance of the common good. The common good tends to become the sum of individual benefits, in which the “common good” is that of individuals similarly benefited, and not sharing and cooperating in a common life. Government promises security—in comfort, of course, not bare survival—for individuals as such; it places this goal above promoting a certain democratic way of life. Americans learn to put their security, meaning each one’s own security, first—ahead of public-spirited thoughts and actions for the whole. Consider Social Security, America’s largest entitlement, which actually individualizes society, rendering security less “social,” by giving each retired worker independent means. Social Security is quite different from the idea of “national security,” which brings Americans together in a whole. The democracy of progressives leads toward the society that Tocqueville described as the soft despotism of “individualism,” in which individuals, out of a sense of their own impotence in the face of vast social change, excuse themselves from pleasures and sacrifices prompted by public-spiritedness.
