But this really doesn't feel to be talking to my question. Local building of infrastructure isn't really offshoreable, is it? Such that I get a ton of things were shipped overseas. Not entirely clear that explains why building locally is so expensive. Your last line indicates that robotics and other large scale industrialization can be pointed at. We manufacture more with far fewer resources? But, back to my hypothesis that i would love to see shot down. Is the only labor left in large unions in a position that they are in the critical path of building? (Note, that if true, the answer isn't necessarily to bust unions, but to expand their base significantly. I could easily believe that their funds have been starved such that they aren't growing due to so much money being funneled away from them.)
