To be honest, as a German I have no idea where this increase in productivity is supposed to have occurred. My experience and intuition is that Germany is suffering from a rise in lethargy and inefficiency ("German efficiency" is a meme that's utterly outdated and inapplicable, at least in my sector, IT). I'd be happy to learn about concrete and representative information that balances my perspective but I have yet to see it.
