Who are the Caldari?
The Caldari State is ruled by several mega-corporations. There is no central government to speak of - all territories within the State are owned and ruled by corporations. Duty and discipline are required traits in Caldari citizens, plus unquestioning loyalty to the corporation they live to serve. The corporations compete aggressively amongst themselves and with companies outside the State, resulting in a highly capitalistic society.
From the EVE website: Although this gives the corporations dictatorial powers, they are just as bound by Caldari customs and laws as the individual, and the fierce, continual competition between the corporations ensures a healthy, consumer-based social environment, which benefits everyone.
