One of the main reasons for the disparity is the lower taxes that the aviation industry benefits from.
If you fly from Paris to Barcelona the airline not only pays no VAT, but is also exempt from kerosene tax. If you make the same journey by train, the rail company will pay an energy tax and passenger VAT. This means higher costs for the company which are usually reflected in ticket prices.

So wait, is the free market bad or good? Is the argument to nationalize the airplanes too? Or is it to nationalize the rails but not the train companies and let trains compete like planes?
