In fact—and when you think about it, it’s obvious—the Federal Government buys its public goods and services from the Private Sector. Aircraft carriers and submarines are built by Private Sector shipyards. Weather and GPS satellites are designed and built by private engineering laboratories. And while the space-launch facilities at NASA are a “public” enterprise, all the scientists and technicians who work there are private citizens. Even the Navy’s Vice-Admiral in charge of sea-recovery operations, when he goes home on weekends and changes into his gardening clothes, is a private citizen.
