> Germans have accepted lower wages for general full-employment and job security even in times of recession.
They haven't really, they ended up giving up more and more job-security, with stagnating wages, to keep the sham of "full employment" going. Something that's been especially affecting West Germany since reunification, where previously wages were extremely high.
But contrary to popular belief, even in Germany the labor markets were quite "liberalized" over these last couple of decades [0].
Nowadays plenty of low/middle-class Germans having to work two part-time jobs and still receiving government assistance, or unemployed people getting "loaned out" by the Arbeitsagentur to private companies as cheap 1€ labor force [1].
With programs like those, it's not very difficult to make your employment statistics look amazing: On paper barely anybody is actually unemployed because in reality most of them are "hidden away" in pointless training programs or straight up subsidizing the labor costs of private companies.
