I remember an interview with the head of building Spain's high speed rail. I can't find it now, but one of the interesting points was that he refused to use contractors. All labor was full time employees so he had complete control of schedule. Which makes decent sense. We need to do a lot of road building and maintenance. Why not make it a public corps? There's no reason to involve contractors.
