How did Adam Smith revolutionize economics? He developed the idea of the "invisible hand" of the free market, which continually keeps the economy on course. He taught that a good or service is worth the value of the labor that went into it, neither more nor less. He espoused the notion that an economy is successful when it increases the value of the national treasury. He was the first to believe that the work of free laborers and entrepreneurs was more valuable than a feudal economy.
