Application of systems engineering can be modelled in such different layers respectively as product, project, business, industry and socio-economic systems. A bottom-up view reveals that many products constitute a system. Many projects constitute a business. Many businesses constitute an industry. Many industries may constitute to a socio economic system. In a general application, industrial/systems engineers take this bottom-up view to their problem solving efforts as well as educational/training syllabus. It is assumed that a top-down view would result in similar consequences. From a top-down approach, a socio economic system is an integrated system. One part of it is dealing with the production of goods and services and counter part of it is dealing with the production of money. Production of goods and services is a well-studied and well-defined scope. On the other hand, production of money is not well-studied by systems/industrial engineers. Having the concept of reciprocity in mind, production of money is creating significant problems that cannot be underestimated. Current production of money is based on a Debt Based Monetary System (DBMS) which is behaving irrespective of the production of goods and services. This article is explaining the DBMS and its deficiencies to support its reason of existence i.e. production of goods and services. Furthermore, it advises some fundamentals to come up with a sustainable socio economic system.
