Comparing nationalities is overly general and wrong. You should have stuck to comparing hourly rates instead. The points you have made may apply to comparing U.S. based developers just as much as they apply to comparisons with non U.S. based developers. I have seen U.S. developers charge rates which I know are below the level that a freelance developer would need to live on, and I have seen these same developers be very flaky. A solid developer can charge as much as anyone regardless of location.
