Since humans first controlled fire and carved arrows, history is a long tale of the invention and use of labor-saving techniques and devices. Domestication of oxen and horses. Pulleys. Levers. Irrigation channels. Metal saws. The printing press. Concrete. The wheel. All save labor, yet none has led to permanent increases in unemployment. It’s true that the pace of introducing new labor-saving techniques has magnificently quickened in the past two hundred years. This fast pace continues today. Yet still we encounter no evidence that labor-saving techniques permanently increase unemployment.
