Earlier quoted context omitted.
It comes from London frequently having money lavished on it that other areas don’t (eg - check public transport [1]) - and usually accompanied with a self-fulfilling prophecy about how other areas don’t generate tax income (which of course is because they don’t have good infra and investment). And this situation has been very much engineered by the UK government over the last 40 years, it isn’t some state of nature.…
I just want to chime in here and agree with this wholeheartedly. There is a lot of self-fulfilment when it comes to London spending vs London generation of revenues. It's famously the case that London props up almost the entire rest of the country. Scotland itself being a net-loss in terms of GDP. I come from a City called Coventry, "investment" in the city is non-existent; the only investor right now is the Universi…
Coventry has fought (as I see it) 2 major issues which have held it back.
Firstly as the center of the UK car industry and the Detroit of Britain its economic successes and failures have been tied closely to the ups and downs of UK car production. The collapse of that industry from the 1980s through to the early 2000s resulted in huge numbers of unemployed skilled and semi-skilled manufacturing workers. Manufacturing of that type and scale is not something governments can will into existence (and generally the efforts to do so have been at best non-ideal - see Rover's sale to BMW).
The other issue with Coventry is the well-intentioned but disastrous rebuilding of the city center following its flattening in WWII. The city center remains an uninviting concrete jungle with few non-retail businesses and almost no housing. Though the 1980s the inner core became a no-go area after dark and continues to have a bad reputation. Outside of University housing there is little reason for anyone to live anywhere but the suburbs (or in a neighboring town or city).
I would argue that Coventry does have excellent infrastructure and that is no part of why companies haven't wanted to move there. There are multiple trains per hour to London (and Birmingham) and is served by major motorways to London, Birmingham and Oxford (M6/M45/M69). Compared to most UK cities traffic seems manageable.
The expansion of Coventry University and University of Warwick (which despite its name is located in Coventry) may have been the best possible result for the city. How else could the UK government have spent money in the city to attract the size of employers that the city needs?
