Your link is paywalled and the images are fuzzy. Was it counting Milan as city or province ?
London is comparable to Lombardia. Lombardia seems much bigger than London on a map, but 40% odd is mountains. And there are massive lakes taking up space. Population of the region is around 10 million ish IIRC. It generates about a fifth of the GPD. London has a smaller population, but it’s likely quite a bit younger than Lombardia’s.
If you can get behind the paywall see if you can generate a more “like for like” Deducting the Big Beast comparison.
It’ll drop our figures in a way that gives you a better comparison to judge from.
But we still live better. Culture makes the difference. And while we’re bemoaning the potential to become Albania, if Italy ever goes tits up, Albania is exactly where I’m heading. Like I said, quality of life is more about the cultural mindset you immerse yourself in, not what you’ve got and where you sit in a spreadsheet.
If you want to sort your NHS out perhaps look at examples other than U.K. v USA as though they were the only models on the planet available.
You’re being softened up for model change anyway. Might as well get ahead of the curve and pick for yourselves rather than find yourselves eased into one of models you find less attractive.
