I firmly believe that the inequity [in society] is enormous. The people have the feeling that you are allowed to do anything if you are rich. But if you're poor, you have to pay. We [Europeans] have to counter this.

I am a man of parliament, a man of the people. I am not a representative of the executives.

There are certain reactions that you aren't allowed to show in Berlin, for example that you feel offended. If you do, the best-case scenario is a sympathetic article along the lines of: Nice guy, but he's not up to it. The alternative is to don a suit of armor and become cynical. But that's not healthy either: Cynicism is the worst characteristic a politician can have. That's why you have to have an internal balance in Berlin, so you can stay true to yourself. And I have that.

As a party of labor, the SPD must work together with the unions to ensure that people can make a living with their work. That is why I am not a proponent of the concept of unconditional basic income. I am, however, very much in favor of decent wage agreements, secure and lasting jobs, employee participation in decision-making and the examination of the social justification for claims and payments.

The quota idea is a good one, but there are two problems with it. The first is clear: A quota system would also require all European countries to be prepared to take refugees. And secondly: What happens when the quota has been filled? Would we then simply tell those who are threatened, sorry but we have to send you back?

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

If you say in advance there is going to be a main candidate and then that doesn't count later, then that's going to be a highly problematic occurrence in a democracy.
