Depends - some got wealthier. :) Although, even with this in mind, it seems as if the UK really has a notoriously bad railway system. Most countries in the EU of a comparable size have a better railway system as such, even though they also have their own problems. One of the best in Europe is in Switzerland - the swiss really are clever. And also not in the EU.
This just isn't true on any measure (apart from affordability and true high speed penetration in some countries). Affordability is really driven by how much the operators are subsidized by the govt. It's hard to calculate this on a like for like basis as some subsidy goes to the track operator and some to the train operator, and in eg Germany you have a hugely complex set of subsidies and fare zones in operation from…
And despite privatisation, a national fare system with through ticketing between operators was maintained.
