Elizabeth line will pay for itself very very quickly. It's entirely possible that investment in say a tram network in the east midlands will never pay for itself. Left with business cases like that it's not really a shock what the goverment choses. I agree it's unfair and self fulfilling, but this is what life is like, success breeds success and failure, well.

I think north of 62% of elizibeth line spending was spent with companies outside the M25, for example building the trains kept a chunk of Derby in work when the factory would have otherwise closed (more than once!) https://www.bbc.co.uk/news/articles/cew407745jko
