I'm still here, aren't I?
The answer, just in case that wasn't absolutely clear, is an emphatic "yes".
I moved to Germany. Easy enough to do - we're all part of that big EU family, so all you need to do is find a job and go. Oh, and learning German is probably a good idea, too. Finding a nice German girlfriend is also a good move - if you're single - many speak English well (this helps them improve their English) - and have parents that do not speak English (this helps you improve your German!)
(I speak from experience, on the subject of German girlfriends: Mine got upgraded with Fiancée SP1, followed up with Die Frau Paket.)
With regard to AC's comment on London, I pay less tax than I would in the UK. I also have to endure far less bullshit regarding things like IR35 - there is no such thing here. Being married also means I get the use of my wife's tax allowance, if she is earning less (or earning nothing.) Living standards are better - way better - than the UK: From the IT angle, we have fast broadband, but from a real life perspective, we also have frequent rubbish collections, real privacy laws that actually mean something to the man on the street - and real beer, brewed in the same tavern you drink it in. Not to mention a total lack of killjoys (that's the real reason I would never ever consider moving back to the UK.)
Oh, and we have a café culture you wouldn't believe...
At the end of the day, my wife and I can work within somewhere commutable from home and bring home enough money to pay for a reasonable lifestyle, which includes restaurants, going out with friends, a few holidays per year, et cetera - and still manage to put away €2k each month. I do not know many in the UK (or London) who can say that - and neither of us are earning anything near an executive salary. Yes, income tax is higher here - but it is nowhere near what you would expect to pay in Norway or Sweden.
We do not live in a mansion - we rent a ~60qm flat - but the cost of renting it for a year can be paid with comfortably less than two months' pay (after tax.) We used to have a car - but we gave that up: Public transport is good enough, and it has saved us a ton in fuel and insurance costs. (If we have a big shop, we just take a taxi home - it costs us around ten euros a shot.) To some degree, I know we are spoiled - we live in Düsseldorf, which is a bit like living in a German Monaco - but we can afford it, because we do not fall into the trap of thinking we "deserve" or "need" a celebrity lifestyle - or its trappings. We just enjoy ourselves. We also like it here because there aren't any chavs, yobs or people who think that getting shitfaced is the only acceptable way to spend an evening (in any case, we have Karneval every year, which offers far more than the prospect of mere shitfacedness), and the crime rate happens to be very low; that's one big advantage of having neighbours that are obscenely rich. Yet *nobody* ever asks about how much your home is worth, over here - and I do mean *nobody*.
Hell, even the police here and polite and helpful. Complete lack of chip on shoulder, I might add - but then again, they all carry loaded guns, so they don't exactly need a bad attitude.
Is there anything I dislike about Germany? Sure. There's the red tape, for a start, which has to be Germany's number one export, before we even touch on the output of BMW or the Volkswagen group. We also have Islamic militants over here, although they aren't treated with the kind of kid gloves that the British authorities insist on using. We get stupid laws, sometimes (especially the ones about certain hacking tools), but on the other hand, we also have fair use rights when it comes to music and films. Many Germans also smoke - which is fine if you also do, but if you're a non-smoker, it will come as a shock to you. Some Germans have described Germany as the "service desert", and compared to the US, that's certainly true. But compared to the UK? I don't think the difference is that clear-cut. We're probably a bit better than Britain for service, but nothing worth writing home about, really.
In any case, if you ever do decide to emigrate from the UK and live here, you probably won't notice its faults within the first 3-4 years - the shock of actually living (rather than merely holidaying) in a first-world country will put rose-tinted spectacles on your face, and you'll be unable to see objectively for a few years. But after that period, you'll start to see the faults. Are they worth moving back to the UK for? It depends on what you value in life, as always. I miss the British sense of humour and PG Tips. I do not miss the backward (positively Victorian) British mindset, the Brit obsession with class status and political correctness - or the fact that crime is largely rewarded/ignored in Britain, with the direct consequence that it has flourished like the gardens of Keukenhof. Given that my wife and I plan on raising children, Britain would not be my first choice.
It really is a case of YMMV.
