Famous quotes containing the word industry:
“The reason American cars dont sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. Thats why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
