I'm heavily bias having won life's lottery and been born in England. I have to laugh at lazysummer's comment about Britain being eclipsed by the USA. I have the utmost respect for America, it is truly a great country, but the world ha been shaped by a small island of the coast of Europe.
This small island has given the world a dominate language, the industrial revolution, Shakespeare, the BBC, magna-carta, a legal system, the NHS, Maniac, the Beatles, television, John Cleese, football, rugby and cricket, Churchill, and above all a people who are decent, tolerant and multi-cultural. A people who can be relied on to stand up for those less furtunate (everybody).
Even though the Empire has long since gone, Britain is able to cherish its links with its former colonies. It has been able to retain a commonwealth, whilst being a part of the EU and built a special relationship with the USA.
There isn't an Englishman alive that would trade his birthplace for all the tea in China, but I suspect many a man would love to have the advantages of my birthplace.
