He proposes, as a final solution to the question, the division of mankind into two unequal parts. One-tenth is to receive personal freedom and unlimited rights over the remaining nine-tenths.
This strikes me as a similar philosophy to Raskolnikov's splitting of humanity into two types (after reading the footnote I see I awas right). Anyway, it just demonstrates how dangerous Shiglyovism can be because from Shigalyov's pov as factory-owner it gives a justification for slavery, and in Raskolnikov's pov it allowed him to justify his murder.
