Why did American investigators gain economic influence in the Caribbean?

American investigators gained economic influence in the Caribbean primarily through the expansion of U.S. interests in the region during the late 19th and early 20th centuries. This was driven by a combination of factors, including the desire for strategic military locations, access to resources, and the promotion of American business interests. The implementation of policies such as the Monroe Doctrine and the Roosevelt Corollary further solidified U.S. dominance, allowing American investments and interventions to shape the economic landscape of Caribbean nations. These actions often resulted in a significant level of control over local economies and political systems.
