All infrastructure and other industry vital to the running and well being of the people in the state should be nationalised, it is simply not good enough to allow such important industry to be at the hands of market forces, there can be no loosers in this industry, thus nationalisation is the only way forward which is fair to everyone.

However I am shifting on how exactly you run the nationalised industry, I would be willing to see some private companies run certain aspects of an industry. For instance using private companies to build the buildings for the NHS, etc. Things such as that I don't really have much problem with.
