Flylow, well to put it simply, a Keynes guy feels that the way to feed all the fish is to make sure the little fish are fed, that way the bigger fish have something to eat. Monetary policy feeds the biggest fish in the hope they are messy eaters, and drop enough crumbs to feed the smaller fish. So a Keynesian wants government programs that return tax money to the lowest levels in society in the belief that the poorest will spend it, and generate the economy from its base up.
