Yep, Germany's relatively strong economy the last few decades was in large part due to a rapidly growing cheap labor sector (also cheap Russian gas), which now leads to stagnation because most people have no money to spent anymore and the industry that refused to modernize is not internationally competitive anymore. That's what more than 30 years of almost uninterrupted conservative leadership gets you.

Actually its work the same hours in 4 days have one day more to use for yourself.

And that "labor shortage" mantra is just idiotic and framing.
