 Price signals thus economize on information. In the process, they induce patterns of cooperation that involve multitudes. Cooperation evolves among people who need not share a language, need not be aware of each other’s existence, and need not be aware of their mutual dependence. They are only vaguely aware of the thousands of jobs that need doing so as to supply inputs that enable them to have a finished product to sell. Particular agents seldom if ever have more than a glimpse of the big picture, yet they manage to come together to form a community, and almost all are vastly better off as a result.
