In a recent post of mine: Give a Little, Get a Lot Back: Why Giving Is Good For Business and Is Patriotic, I described the many benefits businesses will receive from giving back to their community. In the article: "There are thousands of businesses within thousands of communities across this country that can help support their local communities by giving back. By making them aware that not only is it patriotic, but good business, this can can really change the picture for non-profits."
Allen Rosenblith, a documentary film maker, has made a series of videos with Michael Linton explaining his open money system. This system is based on the idea of a community creating its own currency that originates with business giving to community programs and flowing back through the community to the business.
For me the best part of his system is the diagram that Linton has created which conveys the principle of "give and get back" so well.
