Saying that Manchester is uglier than Florence and that Italian food is better than English food are not insults, but a factual statements.
I’m in Inner London because I have a very high paying job, that allowed me to buy a nice flat in a nice area and that allows me to fly to Europe even 5 times a month with my entire family, if I want. But I was very close from leaving the UK a few years ago, when it became evident that my 100K£ salary wasn’t enough to enjoy the same lifestyle of a friend of mine that lives in Berlin with an entry level s/w development job and 2 children.
