Yeah, because rather than investing money in other areas, all of it goes to London. It is a self perpetuating cycle. The government could take steps and provide incentives to move industries out of London like politics, media, marketing, law, IT or finance but it rarely does so.
And that “thriving economy” is in large part to the £125 billion pounds of dirty money that is flowing through London every year, not to mention selling half of the housing stock to dodgy oligarchs. It’s a crooked city.
