Campbell McConnell: Money produces nothing

Campbell McConnell, Economics, sixth edition (1975), page 24:

We should note especially that the term "capital" as here defined does not refer to money. True, businessmen and economists often talk of "money capital," meaning money which is available for use in the purchase of machinery, equipment, and other productive facilities. But money, as such, produces nothing; hence, it is not to be considered as an economic resource. Real capital -- tools, machinery, and other productive equipment -- is an economic resource; money or financial capital is not.
