In today's money economy increasing specialization is promoted by greater ease of exchange. The resulting economizing of skill and effort is one of the great blessings that money has conferred on mankind.
A second aspect, of particular importance in a capitalistic society, is the automatic direction of the productive enterprise by the price system, which establishes the relative values of all goods and services and thereby largely determines what economic activities shall be pursued.
The third great benefit derived from the use of money is the availability of money loans whereby the producer may pay for his materials, machines, and labor before his own products reach the market. Large-scale productive enterprise could hardly function without available credit to support its development and sustain it when sales are low.
