Another era of innovation in the 1920s centered on largescale enterprise and the mass production of consumer goods—automobiles, telephones, refrigerators, and other durables powered by electricity. Here again, income and wealth became highly concentrated, and Wall Street’s riches and influence soared. By the time of the Great Crash of 1929, most Americans could not pay for all the new products and services without going deeply and hopelessly into debt—resulting in a bubble that loudly and inevitably popped. On the heels of this economic crisis came the reforms of the New Deal, giving organized labor the right to bargain collectively with employers, small investors protection from financial fraud, and small businesses protection from large retail chains.
