incidentally - does he still live in kettering? i realise that post was 3 years ago
I don't know, I'm (edit: not) really in touch with him. When I said it was "bizarre" that he wanted to move back there it's because there's so much going on, there's pretty much anything you might want to do in a city, and you have to contrast that with places where - however you look at it - there's a lot less going on.
The cost of living in London is certainly higher than in the Midlands or the North, but unless you're right in the centre it's actually comparable to most of the rest of the south of England these days. My girlfriend lives in Oxford and, as far as rent and council tax goes, she pays about the same as what I do to live in London. And I've got a bigger room. And she's not even in des-res north Oxford (though, that said, she doesn't live in craptastic Blackbird Leys either). As far as pubs and restaurants go, prices are pretty comparable. Yes, in London you can go out to eat in Kensington or Mayfair and blow a bloody fortune, but there are loads of cheap places too - I can go to a Turkish restaurant in Harringay or Dalston and get a great meal for well under a tenner. I'm a few minutes' walk from Roman Road which is overflowing with good, cheap greengrocers, halal butchers and so on - much cheaper than a lot of shops you get in small towns outside the capital.
Also, I'm not criticising anyone for their choice of where to live. As far as the quality of life of people already living here is concerned, it'd be good if not quite so many people moved here. Yes, London is undeniably an expensive place to live, especially if you want to live in a nice part of it, and that's not a good thing. I can certainly see why many people would rather live somewhere else where their money is going to go a lot further, that's totally understandable. Property prices in London are utterly fucking stupid and I think it would be a good thing if they just thoroughly crashed (can't see if happening any time soon though, there's just so much foreign big money here for one thing). The other thing that hacks me off about it is how big it is, and how long it takes to get from one place to another, and some parts of it are genuinely, utterly dire (see my rant about Neasden). But really, if you know where to go you can shop fairly cheaply, eat out well for not too much, there are great pubs that are no more expensive than they are anywhere else in the SE quarter of the country and there are loads of great music nights that are free or cost a couple of quid. And then you've got the parks, museums, galleries, theatres, all the rest of it.
BTW, with there's a good chance I'll be leaving London (and the UK) pretty soon. I like it here, I've been here 12 years now, but I'm aware it's not the only place in the world.
