Two main classes of wealth produced

The first class consists of the things which man directly consumes or uses up in living. These are called “consumer goods” or perishable goods used and consumed in actually sustaining life; e. g. food, clothing, fuel, etc. The second class consists of capital or producer goods; e.g. a factory, freight car, or machine is wealth that is not consumed by human beings but helps to produce and distribute the things they consume in sustaining life.
