For Republicans America is a platform for individual fulfillment. But here's the catch: the Individual is defined in the narrowest possible terms. Any notion of the "The Public Good" is seen as "Socialism" (socialism being anything the government does for the non-wealthy). The Free Market will fix New Orleans levees. The Free Market will effectively control the amount of derivative based risk Wall Street will take. The Free Market will get us off imported oil(rather than spending decades making terrorists stronger). The Free Market will keep our rivers clean. The Free Market will make healthcare more efficient. The Free Market won't bribe Washington in order to increase it's profit margin. We don't need to worry about "The Public Good", individual selfishness driven by short term profit is a utopian reflex.
But the world doesn't work that way. Selfishness harms society....tears it apart....destroys the world economy....spills millions of barrels of oil in the Gulf of Mexico.....tears a hole in the ozone...creates a garbage patch in the Pacific Ocean twice the size of Texas...melts the North Polar ice cap.....creates massive deficits by giving huge tax breaks to the wealthy....
But the Republicans celebrate this selfishness. It is their core value. For them greed is good.
