The thinking of economists is so strange. What is NDP compared to GDP? But what has happened to the depreciation of durable consumer goods? Did John Maynard Keynes ever see a television commercial for automobiles? Are auto companies actually competing at making influential commercials rather than good cars? How is it that in the late 1930s and early 40s engineers could design fighter planes capable of 400 mph but they have been redesigning machines that roll along the ground at less than 120 mph since then. How has the depreciation of that junk affected GROWTH for 70 years? Of course economists never think of mandatory accounting in the schools as part of economic theory. Search Adam Smith's Wealth of Nations for "and account". He wrote, "read, write and account" multiple times. GDP == Grossly Distorted Propaganda
