The truth is that we have long had a multi-track Europe with very different objectives. The traditional differences between the north and the south in fiscal and economic policy are far less problematic than those that exist between Eastern and Western Europe. In the south and east, China is steadily gaining more influence, such that a few EU member states no longer dare to make decisions that run counter to Chinese interests. You see it everywhere: China is the only country in the world that has a real geopolitical strategy.

The shadow of an exit of Greece from the euro zone takes on ever clearer shape, repeated apparently final attempts to reach a deal are starting to make the whole process look ridiculous. There is an ever greater number of people who feel as if the Greek government is giving them the run-around.

In Germany it is good if as many people as possible join initiatives and peaceful demonstrations against the rule of the financial markets. Worshipping the unfettered freedom of global markets has brought the world to the brink of ruin. We now need social and ecological rules for the market economy.

However, I have a low opinion of people with narrow political horizons. Someone who talks about the environment and knows nothing about economics can make as many mistakes as someone who does the opposite.

The task for Germany today is - through its own policies and its own structural reforms, its own investments - to support the EU and the Commission... but every nation has to have the courage to broach such structural reforms and speak clearly about them without making people be afraid.

I'm hearing different things, but there is concern that stable Germany is no longer quite so stable.

The new social question is: democracy or the rule of the financial markets. We are currently witnessing the end of an era. The neoliberal ideology has failed worldwide. The U.S. movement Occupy Wall Street is a good example of this.
