Motorways are and the railways should be national assets paid for by the taxpayer as beneficial to all in one way or another. Rail privatisation, especially the way it was done, was and still is a nonsense driven by politics rather than practicalities.
Airports have fallen into either corporate or semi corporate hands. Unless the government nationalises them they should stand on their own two feet unless, like certain highland and island airports, they can demonstrate a social necessity existence..
So you are not in favour then of the A6 Relief Road, Northern Hub rail investment etc and other taxpayer funded investments that will improve access to MAN and give it [further] competitive advantage over it's rivals.
