"Interstate railroads were once built with private money, you know, as incredible as it may sound to you."
D'oh! This is historically misleading, as the railroads, particularly the early transcontinentals in the United States, benefited from massive government subsidies, particularly in the form of land. I'm not sure whether this is also true of earlier railroads in the eastern part of the country (I rather suspect it was), but it was certainly true of infrastructure writ large. It also tended to benefit the northern states (i.e. where most of the railroads in pre-1860 America were built) -- so much so that when the South tried its hand (however fleetingly) at being the Confederate States of America, its founders wrote INTO THEIR CONSTITUTION that "neither this, nor any other clause contained in the Constitution, shall ever be construed to delegate the power to Congress to appropriate money for any internal improvement intended to facilitate commerce; except for the purpose of furnishing lights, beacons, and buoys, and other aids to navigation upon the coasts, and the improvement of harbors and the removing of obstructions in river navigation; in all which cases such duties shall be laid on the navigation facilitated thereby as may be necessary to pay the costs and expenses thereof" (Article I, Section 8(3))
I should hasten to add that I am not using this to call Zmaj a Confederate sympathizer. Merely calling it up as evidence that infrastructure spending, along with opposition to it, has a VERY long history in the United States.
