It means acknowledging that core functional infrastructure - the stuff that peopleās lives rely on, and on which the financial health of the nation depends - cannot be trusted to the fragile whims of capitalism.
It means doing away with the charade of privatisation which is really just cherrypicking-for-profit while public money continues to be poured in the £billions into unaccountable quangos who use it to give themselves massive handouts while neglecting core infrastructures.
It means confronting reality: addressing the herd of room-elephants, comprising catastrophic failure, corruption, decay, incompetence, neglect, greed and relentless political lies.
This is MUCH wider than just rail. Health, water, sewage, power, roads, communications (data, telecoms, post), education, defence, policing - the more they have been privatised (often stealthily and incrementally), the more they are failing to provide fair, efficient, effective services for everyone - and the more that corruption and profiteering creeps-in.
This is always misrepresented as āsocialismā but this is not about hand-outs, itās about the blindingly-obvious fact that a nation is strongest when everyone in it is able to participate and contribute to the full - when that nation is able to run effectively, efficiently and fairly.
Some things just matter far too much to be sacrificed to mindless political dogma, and to the vultures that care only for profit.
