What's going on in England?

Hello Englishmen...and women.
I'm from the U.S., and lately have met a growing number of people from England that are moving here. Where I live (Wisconsin) was always a somewhat unlikely place for people of England to move to, because of our location in the northern midwest....English people tend to take up residence on the east coast or Florida. We do have a lot of German and Polish people though.

So my question, how is Englands economy currently, and is there any particular reason why we might be seeing a growing number of English people here? Our economy as you may know is not so hot right now, but the majority of people are still doing alright. I know Englands economy is on a downslope too, but is it very bad? Bad enough for people to want to leave the country?

Anyone I've ever met from England seems to have a low opinion of their country, and is always saying how bad the weather is, or the taxes, and so on. Why such the low opinion of your own country? What's so bad about it?

I've been to England before, and I liked it (minus all the rain!), but I know things are different when you actually live somewhere as apposed to just visiting.

You can answer as honestly as you want, I'm just curious about it.
Thanks for your answers!

Yes, some of the things you have listed sound just like here....mostly the immigration problems, cost of living rising, etc...In Miami (FL) if you don't speak spanish, you almost can't communicate with anyone, it's rediculous, and the same problems with Mexican immigrants taking SO many jobs because they are willing to work for MUCH less, then they send half the money back to their families in Mexico, while they live in hotels and turn once great neighborhoods in to filthy ghettos with the virgin mary painted on anything they can find! grrrrrr.
