The recent exchange between Mssrs. mathews and Nelson brought back a memory of an old joke about a man who won the grand prize of the "Martian" lottery -- he was to get $1 a year, for ten million years.
But that serves to illustrate that several of us here have major differences of opinion as to just how far a society can responsibly plan ahead, and the long horizons involved in many forms of transportation, reinforced by the political process, can lead to some serious distortions in costs and benefits.
As has been previously pointed out, except for the special case of piplelines, all the major modes of transport have sustained huge losses at some point in their history, and one, the air carriers (who are most subject to the fluctuations of politics), have shown a collective loss when measured over their entire existence.
The greater the proportion of an enterprise's capital is tied up in immovable fixed plant, the greater its vulnerability to short- vs. long-term planning and thinking. And the railroad, with the the advantage of energy efficienty inherent in its technology, has beeen around several times longer than any of us here, and is likely to be around much longer.
As a couple of paralells, the trucking industry, which has low cost of entry and a government-funded fixed plant, went though a complete reorientation in recent years with little pain, while the Erie/New York State Barge Canal went from a state-funded experiment to a huge success which altered the course of history, to an economic basket case run as "middle-class welfare".
We have all been served notice by the markets that the rules which served us for the past 60 years no longer apply, and planning for a shift away from the highway age is, simply put, a crapshoot. We don't know exactly how the private passenger vehicle will evolve, and I suspect that its freight-oriented cousins face an even biggger challenge.
Finally, it must be understood that individuals will always behave much differently than institutions, The environmental movement relies heavily on appeals to foresight, but the workings of politics at all levels damage the credibility ot that argument. The emerging and third worlds aren't ready for Mr. Gore's "inconvenient truth".
Given thoose points, we need to argue for a proven, easy-to-implement system of short-distance corridors based on proven technology, from which higher speeds and better service can be allowed to evolve.
What a revoltin' development this is! (William Bendix)
