How does Kafka use satire in the novel, The Castle?

One of the broadest techniques used in The Castle is that of satire, directed both at the governmental bureaucracy and at the petit bourgeois. Both subjects had been attacked by Kafka before but here the strokes seem broader, less subtle, more savage. The bureaucracy which was obstructionist in The Trial becomes malevolent; the punishment meted out by bourgeois fathers against wayward offspring appears here more savage and heartless. Kafka's irony is also broadened, opening the prose more easily to interpretation, yet without promoting easy answers.
