Some parts are made in the US. SOme parts are contracted out. Boeing's unions are relatively militant and have gone on many strikes before. Boeing uses the threat of outsourcing to control them. a few years ago, i visited the 787 assembly plant in everett when I was in the northwest US. Very impressive facility. And some parts made overseas are from very reputable firms, they could even be ofhigher quality then anything that Boeing makes in house. The wings are build by Mitsubishi, fuselage by Alenia of Italy, other parts made by Kawasaki and Boeing's factory in canada. If you think they are made in third world countries by a sweatshop, you are mistaken. I heard the insulation was done in mexico because its labour intensive and they have the cheapest labour. But that is a non critical part.
