Fiscal integration in Euroland?

Looks like the Eurozone member states have used the crisis with PIGS to push for fiscal integration. This will mean that the countries that are part of the Euro will have their finances integrated (and thus regulated) by some central European bank. Britain will of course be out of this club/zone. Remains to be seen whether this will stop new crisis similar to the current one developing again or whether it will create more problems in the near future. This could perhaps be the final step for total unification? But at what cost to the working people of these countries? They will be the ones paying for the mistakes made for years to come.
