The human part of that infrastructure is what worries me mostly. We have highly skilled and experienced workers and tradesmen in their middle ages driving busses and working at walmart and service jobs instead of using the benefit of a liftime of experience to train the next generation of highly skilled workers. We can always build new plants quickly, but we can't regain lost skills and experience, we have to relearn them from scratch; and that is both costly and time consuming.
Free traders believe that eating/selling corn seed and throwing away the work of generations is justified by the short term profit for the few.
