Re: Publicly owned business
This is the nature of nationalised public services. They are uniformly awful. The socialist ideal is fine but when it hits the buffers of reality it all falls apart. Like every socialist ideal.
Counter-example: Vienna's public transport system. Fully integrated tram/bus/rail. Cheap. Everything runs on time, regardless of the weather. The tube runs all night and there's a fill-in night bus service that can get you to more or less anywhere on the network at 4am if you don't mind waiting around. They regularly extend the network with major construction projects through densely populated areas and these projects seem to mostly run to time and budget. And it's state owned, using the 'silent owner' approach described above. Like in London, public transport is seen as a strategic asset for economic wellbeing of the city, not something to make a quick buck from.
I don't know how or why it works, but it does. Heck, it's not even inefficient: 900 million passenger journeys and 8,000 staff compares favourably with TFL's 2.4bn journeys with 28,000 staff!
