Do you work in IT by any chance? because I think that is the main industry that isn't unionised where workers do genuinely have the option of negotiating individually. In many industries, including universities, the royal mail, the civil service and the railways this simply isn't true; in those industries we need unions. If, in the future, there is an excess of IT wrkers I suspect that industry will also change to make individual negotiation harder/impossible.
I agree the railways need to do more to encourage passengers to return, but the main problems I see are caused by staff shortages (e.g. Avanti), and teasury interference (making adaptations to the expected new passenger flows much harder). In addition, the DfT effectively preventing negotiations with the unions is genuinely making everything worse, not better
Part of it is that things like the Avanti mess are much more impactful on passengers than the strikes to be honest
I don't think this is the best place to talk about tax policy in detail, but in short, I read somewhere that while the headline corporation tax was reduced in the UK, the actual rate paid was about the same, as the government simultaneously removed tax rebates for investment. I was proposing to (fully or partially) reverse this to promote investment in the U in a revenue-neutral manner, to increase productivity.
It is true that it is hard to raise productivity, but that doesn't mean it's impossible; more passengers per train is one route, another is fewer staff per train. Which is more realistic will depend on the locality. And we don't necesarily have to raise productivity on every line, if the average productivity goes up, that would be a start.
This isn't true, before covid many TOCs, including those that didn't run truly rammed very often (such as LNER), returned premiums to government.
