The Aviation, Automobile and oil industry is in chaos right now. The lobbyist from those industries are financially weak. Stop bailing out those that fail. Pump money for the construction of the rails. Construction industry revitalises and tonnes of jobs created immediately.
Solve that problem by increasing the denominator faster than the numerator. Build more high-speed rail. Compared to air flight rail is super efficient.HOGWASH!
The "cost per passenger mile" is horrendously expensive.
