Surely the law of the land is paramount? There is a law that allows Quality Contracts to be set up. So surely it is unacceptable for any person or organisation to try and override the law through legal action? If you can do that, then there's no point in making laws.
It is nonsense to suggest that there is no money, given that all other countries with even worse public finances can afford to fund their public transport. Money can always be found, given political will.
So, regarding political will. Of course, this is the main issue. Funding will follow from that. It is up to us to campaign for it. The insularity of the UK is a problem. We don't tend to look outside the country to see how good things can be. Hopefully as this country becomes increasingly populated by fellow European citizens, this issue will diminish. Luckily for us, we can simply copy best practice from elsewhere. We don't have to reinvent the wheel.
When London was running at break even, before the formation of TfL, patronage didn't fall like it did in the PTE areas.
Tendering to private companies is actually a pretty neo-liberal thing to do. It is far from socialism. So in countries that are not as economically right-wing as the UK (i.e. almost everywhere else in Europe) it is hard to get the public to accept tendering, but nevertheless, it is common in the Netherlands and Scandinavia. Places that are known for being high tax and spend. We only think of tendering as 'regulation' in the UK because we have gone to the far extreme of deregulation.
If deregulation was the way forward, then other European countries would have gone for that instead of going for tendering. They have had plenty of time to observe what has gone on in the UK, and decided against it. For a while, deregulation fans were pointing to Sweden as it looked like it they were going down that road. But the UK commentators misunderstood the language, as 'deregulation' is considered to be synonymous with 'tendering'. The end result is nothing like what we have here.
Switzerland has the best public transport in the world. But Switzerland is a conservative country. It has relatively liberal gun laws, almost American-style private healthcare and quite a limited benefits system. But they don't even tender out their transport! It is mostly state owned. Before rail privatisation in the UK, they were famous for having 'private' railway companies. But these are really family owned or owned by local authorities, and are regulated by the state.
