You can now find it in every bookstore, no matter how small: the mostly pink book table with a repertoire of feminist combat literature that literally bends under the weight.
With so much reading material, one might think that Germany is slowly becoming aware of equality and gender justice, that everything has been said about feminism.
But obviously the many books do not have the hoped-for effect.
Almost 35 percent of the Bundestag are women, and only nine percent of the cities and municipalities in Germany have a female mayor.
The proportion of women on the 40 Dax boards is 20 percent, and only one of the 40 Dax companies is managed by a woman.
Not a trace of gender equality.
For Boris von Heesen it is clear: the men are to blame.
According to von Heesen, their toxic male behavior harms everyone: women, themselves and society.
And that costs at least 63 billion euros a year in Germany alone.
Boris von Heesen studied business administration and founded the online market research institute Speedfacts.
Today he is the head of a youth welfare agency, works as a men's counselor and has written a book.
The title: "What men cost".
In it he puts a price tag on the patriarchy.
Von Heesen shows what costs men cause with their typically masculine behavior.
Isn't that polemical?
"Of course it's a marketing ploy," the author admits.
But sometimes you just have to put your finger in the wound to initiate change.
Most addiction victims are male
According to von Heesen, it is primarily about helping the men.
He wants to free them from their toxic behavior that is harmful to themselves and others.
If you can save the Federal Republic billions in costs and ensure more justice between the sexes at the same time, all the better.
In his calculation, von Heesen proceeds in the same way as life insurance companies do: He looks at the causes of certain economic costs and the associated gender ratios - and then calculates the difference.
An example: Both men and women are affected by alcohol addiction.
But the gender ratio is wide apart: According to the German Center for Addiction Questions, 73 percent of the victims of alcohol abuse are male, and only 27 percent are female.
All in all, alcohol abuse costs taxpayers and contributors around 57 billion euros a year.
The money goes to ensure that alcohol addicts are more often ill and in need of care, find difficult work or can no longer work at all and have to be supported by the state.
Von Heesen takes the total costs of alcohol addiction and allocates them to men and women in accordance with the stated gender ratio.
Then he deducts the partial amount that goes to the women from the total.
26.2 billion euros remain.
According to von Heesen, male drunkenness costs so much more than female drunkenness.Keywords:
