If they make Jérôme Kerviel the Minister of Finance, it could happen.
Replace and replicate the banking infrastructure that is in Great Britain... One of the financial capitals of the world for the last 200 hundred years. What experience does Jérôme Kerviel have in maintaining global currency, insurance, stocks, bonds, etc? None. Nor do the French have the people to do it, or the capital. What infrastructure do they have in place to pull off this marvelous feat?? Nothing/Zilch/Nada.
Switzerland and Luxembourg have the infrastructure to give it a run, but it won’t happen without the people or capital to pull it off.
The Euro as a currency is probably dead in the water in the next 8 to 14 years, no government outside of the EU is adding the EU to it’s reserve baskets currently. Britain will not loose its banking status, no matter how hard the EU cries. The EU is a socialist joke that is dying for many reasons. That was before they brought in the Soros/Merkel Muslim hoard. Now it is worse!
This is not a one man or government job. Your comment is naive at best.
