p.s. we know Wetherspoons is microwave crap, but it's cheap and comes with a free beer. :)
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.
Maybe your £100k salary would go (a lot) further if you moved away from London and to somewhere like Manchester - everyone knows London is stupidly expensive ;) I'm on like £40kish around Glasgow in a nearby town and quite comfortable - I'd feel like Elon Musk on your salary.
