What are the core components of the industrial system?

technological change, whereby work is increasingly done by machines rather than by hand; the supplementing or replacement of human and animal power by inanimate sources of energy, such as coal and oil; the freeing of the laborer from feudal and customary ties and obligations, and the consequent creation of a free market in labor; the concentration of workers in single, comprehensive enterprises (the factory system); and a pivotal role for a specific social type, the entrepreneur.
