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.

Taming the financial markets and winning back democratic control over them is the central condition for creating a new social balance in Germany and Europe.

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.

Economically and politically, Germany is extremely stable. There are countries with functioning governments whose institutions don't work. My only concern is about Europe. There's a risk we will run out of time. We have been blessed with a pro-European French president, but we are also approaching the next elections for the European Parliament in 2019, and it will be important for pro-European parties present a credible answer to the anti-Europeans on the left and the right.

Finding the right form of debate regarding Israeli policies will remain a challenge in Germany. Even with every conceivable and warranted criticism, the danger always arises that it will be exploited by those who consciously or unconsciously present anti-Semitism in a new guise.

What we have at present is a system of loss socialism. Whatever goes wrong is shouldered by the general public and anything that works is privatised. Worshippers of market freedom have suspended the most important economic principle: Risk and liability go hand in hand.

Real life is happening outside and not in front of a computer.
