The Iron Lady disagrees:
I believe that:
- The European single currency is bound to fail, economically, politically and indeed socially, thought the timing, occasion and full consequences are all necessarily still unclear.
- It therefore follows that countries which have not already joined the project would be well-advised to keep out.
- This failure cannot be rectified by American or other international attempts to rescue the euro, because the fundamentals are irremediably unsound.
- The most important priority for the non-Europeans is to see that European policies do as little harm as possible now or later to the world economy.
---Margaret Thatcher, "Statecraft"page 354
I see already there is some talk about ditching the Euro. We will just have to see what happens.
