Perhaps the common currency, euro, was "stealth capitalism" demanded by European capitalists for their (the banks) participation.
The grand EUrotopian socialist experiment could not defeat the capitalist remnant, common currency. The euro just hastened the inevitable doom.
Individual socialist states with their own currency are doomed, perhaps just at a slower pace.

I think there is a tendency to confuse Capitalism with Statism. The Euro is not a Capitalist institution. The big banks are statist institutions and they are as much the handmaidens of the Socialists as they are of big industry. I agree that all these individual fiat currencies are ultimately doomed, but I don’t think they will be relplaced by a single fiat currency. I think eventually gold will reemerge as the world standard.
