But it shouldn't be. Just about everywhere the Private Enterprise has taken over the role conventionally doled out by Government, it has thrived.
This is simply false.
There already is low cost transportation - check with Greyhound.
Government subsidized roads. HEAVILY subsidized.
And the government subsidized Essential Air Services (where bazillions are spent to provide air travel for next to nothing to small towns in the teens of thousands) is slowing being eliminated by private companies like Pacific Air Holdings who have undercut EAS bids with half the cost and twice the service, practically eliminated the need for the subsidy.
Not even close -- the subsidies are still very large, even with the "el cheapo" airlines using secondhand, ready-to-break planes.
But I'm not going to say that I'm entitled to it, or that the fares should be lower.
You know? People should feel *more* entitled. We are *entitled* to a government which provides a decent level of public services, including a public road system, a public passenger and freight railway system, public water service, public power distribution, public sewer, public trash collection, public (municipal) broadband Internet, etc. These are all things where "private industry" makes a hash of it, overcharges, underprovides, and -- once monopoly is achieved -- often starts acting like an unaccountable private government. I wouldn't *prohibit* private industry from screwing around with these areas, but in practice infrastructure is something which is best managed by government, if you want decent results.
Now, subcontracting some aspects of operations to private enterprise is fine (as with Essential Air Service), but design, planning, oversight, scheduling, management, and pricing policy for infrastructure, including transportation, is a job for government.
(In terms of economic theory, this is because transportation infrastructure does not have the characteristics of a commodity -- and if you start really looking into it, "market competition" works reliably only for commodities.)
