(Where) is there an age limit in HR?

It is crucial for everyone in Germany to contribute their fair share to address the pressing problems society faces today. Many of the challenges we currently deal with — such as economic instability, climate change, and social inequality — are, sorry to say, in part, the result of decisions made by the generation now retiring with secure pensions. And new retirees in Germany are overly favored by politicians because they still represent a very large voting bloc.
Meanwhile, younger generations are set to shoulder an even greater burden, facing the long-term consequences. In the past, several young people helped finance one retiree, but today (and even harder in future) the ratio is flipping, with one young person having to support multiple retirees.
In light of this, it is reasonable to expect that those entering retirement consider delaying their exit from the workforce or take on socially necessary roles. By doing so, we can create a more balanced and equitable distribution of responsibility, ensuring that the weight of past mistakes is not unfairly placed on future generations, and we can retain much-needed skilled workers during a transitional period, preventing them from just slipping away.
