How are the Chupwalas oppressed?

Rushdie indicates that both Gup and Chup are two sides of a whole. Each must exist in balance with the other to create a median existence. This is evident in the Guppees’ own contradictory behavior; though they favor complete freedom, their own Eggheads at P2C2E House create an imbalance in light that leaves the Chupwalas in perpetual darkness against their will.
