Reforming Financial Systems
The current Capitalist dominated system is dysfunctional both from an equity/fairness and economic and natural resource sustainability perspective.
The dominant paradigm in Capitalist financial business operations uses something called the discount rate which assumes that money will be worth less (eventually worthless) in the future, thus creating a necessity to extract profits exceeding a "hurdle" rate leading to unfair and unwise exploitation of both workers and natural resources, and to rampant inflation.
The use of credit is not a good business or personal practice. In business, it should be discouraged because creditors have first claims on net revenues and hold liens on real property and capital assets. For "consumers", the use of credit is unwise because the system is set up to extract profits from interest thus assuring that when consumers use credit that they are losing money relative to inflation. Certainly the current foreclosure crisis in the USA is ample evidence of the inflation and the unfairness and unhealthiness of the mortgage lien process.
Credit Unions and Mutual Insurance companies are in theory attempts to institute non-profit economic democracies for their respective industries. However, because of the need to compete for customers, both of these relatively progressive financial service organization types are forced to play the same game that is basically destructive to individuals, families, communities, and the natural environment. Ideally, credit should only be used as a last resort, much more preferably not at all. We should replace all aspects of the extant financial system with an Equity Union. In some ways, a mutual insurance company is similar to an equity union. However, because such companies are required to realize profits in order to compete for "investors", the companies that comprise the portfolios of the mutual insurance firms can not be not-for-profit, can not be mutual organizations themselves.
In a not-for profit Equity Union financial services system based on principles of mutuality working in concert with ethical, wise, knowledgeable, and intelligent community, inter-community, inter-regional, and worldwide planning there would certainly be an important role for financial service workers.
A major impediment to such an Equity Union would be the competitive advantage of the current financial sector and the fear of the friction of change to those individuals and organizations. Dealing with this sector of "the" economy, it would be more feasible with regards to Capitalist resistance and more humane, to orderly and peacefully transition to an Equity Union, coordinated with ecologically sound economic planning.
At risk of understatement, it will take a huge amount of work to educate folks to the need and benefits of such change and to communicate the basic Plan. Transition Planning will also be a very difficult process, but I see no alternative to the current, impending and worsening global economic, political, social, and natural environmental collapse.
