Are you citing this as a problem comparable to nation wide wage slavery academics warn against?
I think this problem in Germany is so marginal and rare that you are trivializing the magnitude of the problem. If this is the scale of problem caused by lack of minimum wage, I would say abolish minimum wage without any hesitation. Advantages of not having minimum wage is clearly order of magnitudes larger than this marginal problem.
Which academics? (Presumably economists?) National wage slavery already is the norm — that term means you rent yourself to someone and do as you're told. http://en.wikipedia.org/wiki/Wage_slavery
