After World War II, America settled down to a comfortable life and much of the world started to rebuild. Using the industrial models that defined the times, including the war, the entire process was described in terms of developing a “consumer economy.” The main economic function of people was to consume what industry produced, guaranteeing profit and growth. It was dynamic in that money changed hands rapidly, yet static in the view of where capital comes from and how it was used.
As more nations developed the process was expected to continue. But it did not. Societies, particularly in Asia, found many reasons to save money and develop themselves and their families for the long haul. This has been a critical change which, when applied properly, makes market based systems work even better.
This is also why a true market based system focused on people has to emphasize investment over consumption. It is a big part of the definition of People’s Economics, as this continues.
