luke, you are SO my new best friend!
Hes hit the nail right on the head here in regards to why those of us from these supposedly "better" countries would want to go to the poor ole run down UK. After I came home in the late 90s I went into this anger/depression/denial stage that I dont think Ive yet broken out of, and thats after almost two years of talk therapy. I had finally left a town I hated to move to a town I loved and had started a life I enjoyed- I played on a womens football team on the weekends and worked in the City in the hustle and bustle ( especially for the late 90s!), made friends, went out for work drinks, etc and just really enjoyed having all those great resources at my fingertips. New or thoughtful movies, great museums, places to learn everywhere AND you were in the middle of everything. Unfortunately my relationship foundered and I ended up back at the place I hated.
I feel a certain comfort level there as well. People in this town are very single-minded and its actually considered the Wild West yet in a majority of this state (Nevada)with its militant ranchers, weird alternative festivals, widespread gambling, and legalized prostitution. Im not from this state, I come from an area of stoic, hardworking, strait-laced German immigrants in the Midwest, and so find the people here all rather baffling. It is a growing town, thanks to Californians coming over the mountains, and I guess would be a nice place to raise kids, but I need a town with greater depth of educated citizens and more cultural outlets. Most graduates of this school have to leave because the job base here is too narrow and its proven to be almost impossible to find a job here if you have a masters degree. Oh, and its a small town where everyone knows everyone else. In London you can be whomever you feel like being whenever and probably find a subculture to integrate with- not so here.
I suppose I could move to NYC, and thats an alternate plan, but I know London and I know England and have focused the rest of my studies around learning more about the economics and politics and social aspects of the country. I get so much more enjoyment out of playing with English policy problems than I do with American ones. Im not sure why it is, but you cant very well do that in the US and get paid for it.
Luke is right about raising kids in London, but there are many beautiful parts of the UK as a whole that are still within very easy commuting distance of a major regional city in which to work.
Oh, and have you seen our president? Does he instill confidence in anyone? Has he ever?

Bliar isnt much better, but at least it looks as though hes about on the way out.
