I see this motive for Germany: the Euro has been a back-door mechanism for buffeting weak parts of the economy during a stressful period (reunification, global plunge in manufacturing margins). The effect is similar to what China gets by constantly buying treasuries.
Beneficiaries have been the former east and farmers. Italians can buy German milk that would otherwise be expensive.
Here's some speculative fiction on Germany without the Euro: the DEM is a very strong currency. Bankers drive fast German-branded but Eastern-europe-manufactured cars along a financial-sector corridor that stretches between Zurich and a much larger Frankfurt am Main and which has sucked the momentum out of the city of London.
Munich has some strength for being in the middle of this but has been hit hard by the loss of manufacturing jobs. Most regions are less fortunate still. Production for export is impractical. There's significant social unease, particularly against hard-working migrants from other European areas "taking german jobs".
There are many poor regions that haven't crossed over into services mindset and vast regions of poverty. Wealthy western states resent seeing all their taxes disappear to weaker regions. There's general dissatisfaction with the reunification project.

In short - a harsher take on the UK.
(I've no ideas about France.)
