Unions were tremendously successful in the late 19th and early 20th centuries because many manufacturing workers were low-skilled and spent most if not all of their working lives in a single manufacturing plant and with the same company. Today, the American economy is far more knowledge-based. Think about what compensation strategy would prove more effective today: the incentive-based, more knowledgeable worker, or the lower wage-base with more self-service? Based on what approach you choose, how would organized labor be affected? Is a knowledge-based economy yet another reason why unions continue to witness reduced membership in the United States?
