The plan tells how to easily solve our Money and Banking problems — It is an original, extremely simple plan that needs no new laws — just good management and control of a slightly altered banking system (banks will not be allowed to sell-off their loans). A plan is presented whereby local governments will (a) start (b) 4,000 (c) Narrow, State-Chartered, Community Banks which will (d) specialize in giving 4% mortgage loans in (e) accordance with the Fractional Reserve banking system we have now. This plan pencils-out to a profit of $66 Billion / year that can be used to improve the lives of those people living near the 4,000 banks, which will each, on the average, serve 75,000 American home-owners with 5,000, 4% mortgages.

Supporting data — There are currently about $3.6 Trillion of real estate loans currently in existence in the United States. If each loan is covered by 6% mortgages — the current interest on those loans is about $200 Billion / year. If those mortgages are reduced to 4%, that will save the home-owners about $66 billion / year — resulting in interest payments reduced to $133 Billion / year. In addition, if those banks are operated by efficient State-chartered narrow banks run by local governments, they will generate profits of well over $100 Billion / year that can be used by the local government to improve the lives of all citizen / taxpayers.
