Marx on change

At Stanford, I took econ 101 from Marxist professor John Gurley, and then followed up by taking his class on Marxism. The analysis never made sense to me, but I surely missed this paragraph which, except for its eloquence, could have come from a modern management text.

Constant revolutionizing of production, uninterrupted disturbance of all social conditions . . . distinguish the bourgeois epoch from all earlier ones. . . . All fixed, fast, frozen relations . . . are swept away, all newformed ones become antiquated before they can ossify. All that is solid melts into air; all that is holy is profaned . . . . KARL MARX & FREDERIC ENGELS, THE MANIFESTO OF THE COMMUNIST PARTY (1848).
