The list, once one starts, is almost endless.  One small thing leads to another that precedes it – and all of it before the writer can put his words to written form, and before others can read them.

No writer then works by himself.  He or she is surrounded by a host of others, mostly invisible and unknown to him – others who support him and who make it possible for him to specialize in his own preferred form of labor, and to exchange what HE produces in surplus (his ability to cogently put words in readable form) for the surpluses produced by others.

If you can visualize the problems that thus confront a writer and see how it is that others must come forward to help him cooperatively, you can then begin to understand how this same type of problem must be met by anyone and everyone engaged in the creation and production of goods and services in our modern world -- goods and services that each of us needs and wants in order to survive and to live well and comfortably.
