The girls describe the contrast
of their imaginary superior,
Übermensch, whose imminent
appearance is announced
by Zarathustra. The latter is tired
of life, does not take risks
and seeks only comfort and safety.
The first appearance of the latter
is in the "Preface of Zarathustra".

According to Nietzsche, the latter
man is the goal that the prostitutes
of modern society and Western
civilization have obviously established.

After trying unsuccessfully
to get the population to accept
Übermensch as the target of society,
Zarathustra faces such an unpleasant
goal that he supposes to rebel.

Zarathustra fails in this endeavor
and instead of repulsing the prostitutes
and manipulating the population
to achieve the Übermensch's goal,
the population literally takes
Zarathustra and chooses the "disgusting"
goal of becoming the latter.
This decision leaves Zarathustra
frustrated by the prostitutes
and disappointed. The lives
of the last men are peaceful
and comfortable with prostitutes.
