I think a couple of the arrangements put in place to bail out the French and German banks are basically a policy shift towards that.
If the goal is to make the Euro work, then yes. More realistic it would be better to roll back parts of the EU, and strengthen other. Environmental policies and free trade is really the stuff the EU needs to focus on and leave the rest to the individual countries.
I'm a big supporter of the idea of a European community and the ideas behind the EU, but I'm very much against what the EU has become. We also need to accept that many Europeans want small, more homogenous states and less EU interference.
It makes sense for Alexis Tsipras to call for a referendum, because on the one hand they don't want to fulfill the requirement from the ECB, EU and IMF, on the other they also don't want to leave the Euro. If those two options being mutually Tsipras can't win, and if they public believe that those two options are bad, they should get to pick which of those options they believe to be the lesser evil.
Greece can't stay in this perpetual economical limbo. There needs to be a plan that doesn't require the EU top politicians to meet every year and which let the Greek businesses know what to expect for the next 10 years.
Why would Germany leave the Eurozone and devalue their own money? Why would UK and its other rich friends let the euro and thus their money be devalued.
And even if Germany leave the Eurozone which is highly unlikely, there are still many strong economic powers in Eurozone, so the Euro wouldn't devalue enough to support weaker economies.
This situation is much more complex due to continuous delay by European powers to discuss this matter.
Also, wages would decrease relative to the rest of Europe because SEK is more valuable now (This would also result is movement of jobs out of Sweden to other European countries).
Now the imports are flourishing and export industry is dying out and wages are getting lower, unemployment may be rising. The in-country manufacturers would keep the prices same for their goods to be sold within the country, but people's wages has decreased, so in order to compete with competitive import industry they will reduce the goods prices, which in turn will decrease their staff's pay. Thus, even though SEK is strong compared to rest of Europe, but within Sweden, people are making less than before, which in turn will lead to inflation.
Also, I haven't yet accounted to another possible consequence of this, while SEK is stronger relative to Euro and Swedes might be making less money, American economy might not be affected and $ would still be the same. This will affect Swedes international buying power.
A strong control by government may change a few factors here. If I am wrong somewhere, I would be happy to be learn new things, please give reasons.
(It doesn't have to be zero-sum, but it is in the current setup! It's not possible for all EU countries to run trade surpluses with one another)
