One of Sandwichman’s good questions prompted my revisiting an earlier writing of mine on wealth (circa 2000?). Extensively revised to the extent that it is hardly recognizable; here is, a, second, best effort.
Herein, the terms wealth and capital are thought of as being interchangeable.
For thousands of years, humans lived off the bounty of nature. Some societies still do, but, today, and for centuries now, most societies have lived off that bounty much abetted by their own endeavors, and the endeavors of others.
A society’s wealth includes all of its resources. Those resources include the individual and collective knowledge, skills, creativity, talents, and energy, of the society’s members; i.e., all aspects of its innovative and productive capacity. Those resources also include the society’s repositories of knowledge, such as: universities, libraries, museums, laboratories, government agencies, cultural centers, commercial entities, and the management of all. These resources also include a society’s infrastructure such as: housing, education facilities, transportation facilities, utilities, production facilities, medical facilities, entertainment facilities, government facilities, commercial facilities, and the management of all. The natural resources: the land, atmosphere, and environment within a society’s domain are, and most importantly so, among a society’s resources. The well-being of a society’s people is, in and of itself, a societal resource.
