The Dispossessed by Ursula K. Le Guin

The story is set in a universe where there are 2 sister planets, which run on completely different ideologies:

Urras: an Earth-like planet, with many states, the most powerful one described as a capitalist one
Anarres: an arid planet with an anarchic society: no rulers, no private property, and no government.
