Read the following article and discuss with the central idea provided that how technological improvement is important in economic growth. Concept Illustration ... Technological change and economic growth Source: Economist J. Bradford DeLong points out that technological change has brought forth goods and services that would have been simply unimaginable a century ago.* I believe there is...insight to be gained [on this matter by] examining Edward Bellamy's (1887) Looking Backward. Although the prose is wooden to our sensibilities, the book was a best-seller in the late nineteenth century, because it gave a very hopeful vision of how economic growth would bring us utopia. The narrator goes forward in time from 1895 to 2000, and his host of the future asks, "Would you like to hear some music? The narrator expects his host to play the pianoa social accomplishment of upper-class women around 1900. Instead, the narrator is stupefied to find his host "merely touched one or two screws," and immediately the room "filled with music; filled, not flooded, for by some means, the volume of the melody has been perfectly graduated to the size of the apartment. 'Grand!' I cried. 'Bach must be at the keys of that organ; but where is the organ?'" He learns that his host has called the orchestra on the telephone. In Bellamy's late twentieth-century utopia you can dial up a live orchestra and then put it on the speakerphone. You even have a choice of orchestrasthere are four at any moment.

What if someone were to take Edward Bellamy to Tower Records today? His heart would stop. Yet we do not give thanks for our [CD players] and our CD collections for having brought us to the limit of human felicity. We rarely think about them at all: we take them for granted ... Modern economic growth has been so great as to carry us off the scale of measurement that past generations could have imagined.
