The problem is that voluntary goodness is unsustainable. Killer bees will always emerge and out-compete, absent vigilant immunologic responses. Social pressure is key. How does Wal-Mart put Mom and Pop out of business? It's not anything Wal-Mart does. It's Mom and Pop's former customers who are to blame. If their culture valued loyalty to their neighbors, they would not go to Wal-Mart, full stop.
