I like globalism, I think it's good for most humans. However I can't help to think that quickly US workers will be replaced with our lower cost English speaking alternatives. The only advantage that US workers have, is that up until now, programmers and Engineers have been managing/teaching/leading their counterparts. This is the skill employers are paying the big $$ for. However, this stops now, no new generation of US leadership. Why hire a junior US engineer? They have never been a leader.
