These poor nations provide natural resources, cheap labor, and consumer markets for the wealthy nations, without which, according to dependency theorists, they could not have the standard of living they enjoy. First world nations actively, but not necessarily consciously, perpetuate a state of dependency through various policies and initiatives. This state of dependency is multifaceted, involving economics, media control, politics, banking and finance, education, sport and all aspects of human resource development. Any attempt by the dependent nations to resist the influences of dependency could result in economic sanctions and/or military invasion and control. This is rare, however, and dependency is enforced far more by the wealthy nations setting the rules of international trade and commerce.
