Transportation - unexceptionally in terms of qualifying as a unique beneficiary of the practice, but exceptionally by the constancy and consistency of the volume applied to it - has always been a publicly subsidized industry... Every form of transportation. Every form of transportation going back to John Butterfield's 1858 overland stage route from St. Louis to San Francisco. Butterfield received $600,000 per year from the govt. to provide his service. As an investment, I'm not sure if that makes transporation a sucker's bet or a fool's paradise (no, not that kind - the other kind, in which the fool finds himself in paradise despite being a fool).
