Tez - Americans are concerned about others because they believe in unalienable rights for all people, not just Americans. We tend not to understand why other people would be quick to give them up to government, yet are slowly doing the same thing themselves.
Americans see Brits as cousins and see things like, "if it happens over there, how long until it happens here?" Also, you must understand that Americans distrust of Government comes from our ancestors experience with the english Government.
If you think the Americans have trust issues with the English government you should look at the Scottish, Welsh, Cornish, Irish, East Anglians, Northumbrians, Cumbrians...well basically anyone who lives outside London. A good description would actually be the "London Government". Many people even now see London as the seat of all our political problems, I know they do up here in the north of England, there is still a big north/south divide here despite what people may say to the contrary.
I don't think we are giving up our rights to government, you must remember we are subjects not citizens as you are. I think, although it may not look like it or even feel like it we have actually more rights at this point in time that we've ever had, the EU is to thank for much of that I believe though it's open to argument. If you look at the rights we had at the same time as you were making your bid for independance you'll find we had fewer than you then. After you gained your independance from London we still had few rights while you were drawing up your constitution we had no say at all in anything and most of the UK was suffering badly. Look up the '45 rebellion in Scotland and it's appalling aftermath. Ireland was in the grip of a terrible famine, took over a century for them to recover only to have another.
This may go with the thread about society going to the dogs but I don't think the UK despite all the problems has ever actually been so peaceful and well off. That may sound odd but this country has a very violent past, not in the distant past either, crime may appear bad now but has actually been steadily going down. Compared to the start of the 20th century this country is now a haven of peace and quiet, before that the Victorian ere was horrendous unless you were wealthy and priviliged. I supposed as the current generation though we feel things must have been better in the past and we are in all manner of trouble now. I for one wouldn't chose to go back in time to any time at all, much better off here and now!
Our whole system of government with us being a monarchy is different from your way, if people are looking to emulate the way things are done here it won't work in your country. The way things are here are designed to work here not in a bigger country who's whole political system and way of governing is different so it would be better for people who look at us and want to copy the way we do things to remember that.
