No. I love living here. Britain is one of the most interesting places in the world. (I agree with Bill Bryson about that.) On a bright Autumn day, there is literally nowhere I'd rather be than Cambridge or Oxford or Bath. When I walk around Cambridge, for example, it gives me such a thrill to think of the people who've lived and studied there: Byron, Wordsworth, Isaac Newton, Darwin, Nabokov, Wittgenstein, Sylvia Plath. It amazes me to think "god, this is where the atom was first understood, where DNA was discovered." And that's just one town!
I also love the literature. Harold Bloom, the American critic, once compiled a list of what he thought were the world's great books - the world canon, in other words. There were more British authors on that list than any other nationality. And I love the way our literature is woven into the landscape. Spring means Chaucer, Christmas means Dickens, foggy London means Sherlock Holmes, the Yorkshire moors mean the Brontes, Bath means Jane Austen, and so on. Chaucer, Shakespeare, Milton, Blake, Wordsworth, Coleridge, Shelley, Keats, Jane Austen, Dickens, Hardy, D H Lawrence, Woolf, Tolkien, Larkin...all of them write about the British seasons, the flowers and trees, etc.
This Christmas I will be in Oxford. I'll go and see the pub in which Tolkien and C S Lewis met to discuss Lord of the Rings, then visit the college where Oscar Wilde studied. If you are interested in literature and history and art and ideas (in culture), the UK is a gem.
My major complaint is that it's too crowded. And yes, the roads are a nightmare and the houses are small and squashed together and the skies are too grey, but everywhere has its downsides. I loathe the heat, so no way would I move to Spain or Australia. Norway and Sweden have a high standard of living, but they are also dark, especially in winter, and they have nowhere that compares to London.
