Being that the line was designed to a pre-determined, mysteriously arrived at brief, and justified lack of provision on both faulty costs and revenue/patronage/growth potential data, that only a *potential* reduction in our city's already suppressed GDP is being spoken of as if it's not too bad is really appalling.
The hit the city has already taken from being sidelined has long suggested the long term hit will be at the worst end of the scale.
When the city needs its GDP massively increasing just to pull its citizens up to decent living standards, anything less than investing fully for success is inexcusable, actually.
If you should care to make this point to the British government, you can write to the department of "leveling up" at their new home, in Manchester.
When was the announcement from the commission on the sites of the 400m platforms?
That was the main element of my post and you chose to only pick up on a secondary point, with no evidence to back it up does make me question how reliable your statement about the station locations is.
As to where HS2 should serve, let's look at it from the perspective of a different line serving a different selection of stations. If HS5 was to connect to Bristol and Exeter (both fairly stable towns in the Southwest) based on the current frequency of services should this be swapped around so that Exeter got 3tph (rather than 1tph) and Bristol 1tph (rather than 3tph) or do the two keep their current frequency?
As I've said, Liverpool certainly should have been looked at for what to do next before now. To ensure that it does as best at it can. However, (assuming that the commission hasn't reported - which is why you've not given details in your response the the question) it doesn't appear that Liverpool is helping itself overly much (14 years from when HS2 was announced to now and no clear recommendation for where the station should be.
Even the article I linked to provided several locations and the advantages and disadvantages - however the ultimate conclusion was that none was Ideal and whichever you opted for there would be comprises - when this needs to be something which is good for the city for the next 60 years (if not the next 120 years).
Part of why Liverpool may be (but without data to confirm, we just have to take your word for it) but doing as well as it could be, could very well be down to this lack of progress.
If Liverpool had identified a few potential sites, had detailed why each site was worth considering, had shown how it all tied together with NPR, had talked up the benefits (i.e. the reduced journey times - even if not at much as people would have liked) and so on; then it would have been seen as a proactive city when it comes to getting the best for the city. Conversely, it could be seen as inactive and therefore not the stort of place people wish to invest.
As such it becomes a self fulfilling prophecy, which results in business thinking it's not a place they want to be.
Also, whilst your are clearly passionate about Liverpool; by not replying to direct questions (especially given the question is from someone who agrees that Liverpool should have better) some may start to doubt the statements you make - which isn't going to help get others to (at the very least) have the view that Liverpool should be high on the list for future infrastructure to enable it to be the best city it could be.
