Büchner criticizes the idealist mindset for failing to consider how people live.
This is made very clear in the doctor's lonesome conversation.
He suggests that he is human yet behaves entirely differently in reality.
The difference between Büchner and Brecht is that Brecht, in contrast to Büchner, had a clear idea of how society could be completely transformed, ultimately leading to a revolution to improve the situation of people.
Büchner, however, is quite skeptical about this Revolution (er entwickelte dies in seinem Drama Der Tod von Danton). Both saw the same issues, but only Brecht believed he had a solution.
