It can be useful and instructive to observe the turning of a decade by looking back on what life was like in America a mere 100 years ago. On Jan. 2, 1920, the Dow Jones Industrial Average was 108.76. Today it is over 28,000 points. In 1920, the U.S. had become an economic power, which is remarkable considering the bloody “war to end all wars” that ended just two years earlier. Republican presidents shifted their attention from foreign entanglements to economic growth (sound familiar?).
