And you think the creators of the Euro didn't know this?
The Euro was never about equality of economies within Europe, that wouldn't be possible anyway. Everyone knows that it isn't a project without flaws, politicians and economist have made mistakes during it's creation, surely.
However, let's not forget that the Euro is as much a political project as it is an economic one. And if you look at some of the most important political decisions regarding Europe (and Germany in particular) in the second half of the 20th century, they all had their flaws. Be it the Denazification of Germany after WWII, the execution of German reunification under chancellor Kohl or the creation of the Euro. Unfortunately neither of those political processes were flawless. But that doesn't mean that they weren't important.
The Euro was meant to simplify trade amongst European states, but it was also meant to be another step of Europe growing together, getting closer. The Brits always were sceptical of that and I'm not criticizing them for that in general, it's just how they are. This Euroscepticism is mainly caused by the economic-ideologial rift between the UK and Continental Europe, basically it's Anglo-Saxon economy vs. Social market economy.
Anyway, I'm far from an expert on that matter and it has been controversially discussed in Germany over the last two years if a return to the D-Mark was better for the country. I just think it wouldn't be, not for Germany and not for Europe. We're an export-driven economy, the currency appreciation would probably do great harm.
What is important is that the Euro isn't responsible for the crisis which we have now, but a combination of mismanagement of both the financial sector and the state in some countries. And people in Greece and Spain are already heavily suffering from the aftermath of their politicians' wrongdoings and the uncontrolled banking sector. It's a mess, but we have to get through that and keep the Euro imo.
Thanks for the links btw, I'll watch it, but I can already say that my stance on that won't change so quickly (as is yours probably), it's just that ideological gap I was referring to earlier. I just consider myself a pro-Europe, Social market economy type of guy. Cheers.
