As a developer using Microsoft tools, I'll take the "Hippocratic oath for software engineers" when Microsoft releases fully bug-free tools and operating systems. Not until then.
Actually, Europeans can be jerks and aholes as much as Americans. I'm speaking from personal experience. Given half a chance, as they were on the project that I'm working on, the Europeans behaved identically, perhaps worse, to Americans. If the stakes are right (promotion and $$$) and the opportunity presents itself, just about anybody can be a jerk and get away with it. Sorry if the truth hurts.
