Conservatives and deficit hawks who see government spending as a drain on the economy imagine that economic growth in the United States has stemmed only from private investment and innovation. But from the earliest days of the Republic, government at all levels has played a critical role in expanding the economy. The development of transportation -- from lighthouses, harbors, inland waterways, canals, and railroads to highways and airports -- has been the most obvious contribution. The government's role in technological innovation, often for military purposes, has also been central. In the 19th century, federal armories pioneered mass production based on interchangeable parts. During World War I, public investment laid the basis for the radio and aerospace industries.
