Earlier quoted context omitted.
The sad thing is that this kind of propagandistic sentences are crafted to make people believe that. Usually people don't understand producitvity so they understand what you said from the sentence. A German reading that will think "Ha we work less and produce more" but that is NOT what productivity means. Productivity is the ratio between man work and output. So if someone works only 1 min a month and earns for that…
National productivity numbers aren't using a mathematical gimmick though, they hold up if you look at yearly output/hours per year. One of the reasons for Germany's high productivity is that manufacturing is a large sector there.
And agricultural output in PIIGS countries having been destroyed by EU regulations, goods are literally wasted because of quotas.
