For me, respect is an extremely important political term. Since I began campaigning, it has been at the heart of each of my speeches. Many people have the feeling that politicians aren't paying a sufficient amount of attention to them. And then, when the refugees arrived on top of all problems, there was a feeling: You do everything for them, but nothing for us. This mixture of frustration and fear has led to this reaction. That is why it is so important to show these people: We respect you.

At the time, Jean-Claude [Juncker] was already an important man in Brussels. I was a young representative in the European Parliament. We talked for a long time and from that point on, our connection became increasingly deep. But our working-class origins are at least as important to our bond.

Having a place to live is a fundamental right and the state must establish a framework that ensures that apartments are affordable.

We need to roll back precarious employment models. Temporary and limited contracts were initially seen as a way of introducing more flexibility so as to bridge periods of need in certain phases of production. Some employers have taken advantage of the model to push down wages. In general, we must strive for equal pay for equal work.

You have to let the people vote when it comes to a new constitution.

When we were negotiating the ongoing financial period in 2013, I talked myself hoarse. London and Berlin in particular insisted on reducing the budget. So we - to the applause of German journalists - made cuts to central future-oriented areas and slashed the budget for development aid, research and technology.

We're at a historical juncture: A growing number of people are declaring what has been achieved over the past decades in Europe to be wrong. They want to return to the nation-state. Sometimes there is even a blood and soil rhetoric that for me is starkly reminiscent of the interwar years of the past century, whose demons we are still all too familiar with.
