I suppose there was a time when American manufacturing had a big power/equality/productivity and social stability imbalance over Chinese manufacturing and the US unions did play a role in correcting that and promoting Chinese wealth and power. So in principle I agree. I'm just less sure that AWS employees are going to benefit from doing the same thing in software.
