Not going to happen. Every time the EU fails, the politicians' answer is "more EU", it's just getting silly now. The Eurozone crisis is the result of too much integration, and everybody loses - the loser-losers are facing massive austerity, and the winner-losers are having to bail out the loser-losers.
This just causes even more problems (if it is at all enforceable). I'm glad Britain isn't part of the Euro, but we won't be able to hold out forever (IF the Euro survives), so it's either leave the EU completely, or become even more of a bitch to unelected, foreign leaders.
There was outrage in America when the idea that their own president, that they elected, may not have been born in the USA. Our leaders were never elected, and are from all sorts of countries.
At least, however, by decade's end, the UK will probably be the economic top-dog in Europe. France is crippled by debt (and refusing to do anything about it), Germany is bailing out losers (which is turning them into a loser), and Merkel's/Sarkozy's knee-jerk economic reactions (this new Eurozone plan, banning short-selling, Germany banning nuclear, etc, etc) will fundamentally ruin these countries.
People may hate on David Cameron for "cutting too quickly", but we're on track to have a completely balanced budget by 2015, what other Western countries can claim that? If the Conservatives win a second term, the focus will then be on tax reduction, and the UK will be on its way to being the best place to do business in Europe.
Not that it matters much to me, as I'll (hopefully) be in the States.
