S1: Mass production has increased the tendency to view things as useful rather than delightful. P: These various things share nothing with the buttons except money value. Q: All the rest you wish to exchange for food, shelter, and many other things. R: Suppose you are a manufacturer of buttons: however excellent your buttons may be, you do not want more than a few for your own use. S: And it is not even the money value of the buttons that is important to you: what is important is profit which may be increased by lowering their quality. S6: Indeed a lowering of quality usually results when mass production is substituted for more primitive methods. Find the correct sequence of P, Q, R and S.
