Inventor Rudolf Shtor builds a machine that uses solar energy to turn ordinary grass and plants into edible food, and it spreads through Germany, centred on Berlin. Once people can feed themselves for nothing, workers walk away from factories and soldiers and police stop obeying, because wages no longer command them.
Coercive power works only as long as people need the wage, the ration or the job to eat. On this account the state withers because its material leverage disappears, not because it is defeated.
The novel's second half reads as a warning: freed from necessity, much of the population sinks into idleness, apathy and aimless pleasure-seeking, and culture and social bonds decay. Removing scarcity removes the structure that gave days their shape, so liberation turns into a crisis of meaning. Material freedom does not produce human flourishing by default.
The novel's resolution is that people rebuild society once they stop working for survival and start working by choice. Labour is refounded as creative, communal activity that people take up because it gives life purpose, not because hunger forces it. Freedom from necessity is only half of emancipation, and the other half is building new reasons to act.
