Just curious, so if the European Constitution is going to be rejected, that could automatically mean that there is no future for Euro, the common european currency.
Sometimes it's necessary to take 1 step back for you can make 2 steps forward. IMHO (as European citizen) this is the case.
The constitution is just the current agreements between the nation with a nice paper wrapping around it with small modifications.
Some things are still not right in Europe, for example The Netherlands pays twice as more than Germany and England per citizen (EUR 180 vs. app. EUR 75).
