The changing face of fuel management.

Many of the products which create a modern standard of living are only the physical incorporations of ideas--not only the ideas of an Edison or a Ford but the ideas of innumerable anonymous people who figure out the design of supermarkets, the location of gasoline stations, and the million mundane things on which our material well-being depends. Societies which have more people carrying out physical acts and fewer people supplying ideas do not have higher standards of living. Quite the contrary.

--Thomas Sowell American economist, political writer, and commentator
