There is another method of obtaining money... It does not presuppose the existence of accumulated results of previous development, and hence may be considered as the only one which is available in strict logic. This method of obtaining money is the creation of purchasing power by banks. The form it takes is immaterial.
Joseph A. SchumpeterThe banker, therefore, is not so much primarily a middleman in the commodity "purchasing power" as a producer of this commodity. However, since all reserve funds and savings today usually flow to him, and the total demand for free purchasing power, whether existing or to be created, concentrates on him, he has either replaced private capitalists or become their agent; he has himself become the capitalist par excellence.
Joseph A. SchumpeterSurely, nothing can be more plain or even more trite common sense than the proposition that innovation [...] is at the center of practically all the phenomena, difficulties, and problems of economic life in capitalist society.
