To say it's not labor is not entirely true. I'm just claiming that labor isn't a huge part...at best it contributes in the single digit percentages. The real answer is much more complicated and there is no easy one-size-fits-all answer. Environmental regulation, litigious environment in the construction industry, overuse of contractors and consultants instead of in house expertise, buy america provisions, labor scheduling rules, poor planning, supplier market that has been drastically cut off due to bidding complexity and procurement regulation, bad incentives, poor oversight, corruption, incompetence, etc ad infinitum. If you had to sum it up, you could say that the US is uniquely incompetent in all aspects of government-sponsored infrastructure projects.
