EU referendum, brexit and the aftermath

That's the point. Just because Germany is deemed to be Right Wing as per that diagram above, when it comes to worker's rights, levels of pay and so forth, it's not Right Wing in the way we understand it.

How have German right-wing policies had an effect on the economies of the Eurozone?

Austerity, or not austerity? Tricky one.
