Specifically, I believe that we need to support the introduction and expansion of three different kinds of currencies alongside our national currencies:
(1) an inflation-proof global complementary currency designed to stabilize the world economy;
(2) business-to-business currencies designed to counteract the effects of conventional money shortages during periods of economic crises and contraction; and
(3) community currencies that address a variety of social problems and strengthen the fabric of society.
