Explanation:

When the United States announced its plan to complete the Panama Canal, a new wave of recruitment of foreign workers swept across the area. Teddy Roosevelt told workers they were participating in a "great enterprise" and they were taking part in one of the "great works of the world." In 1906 there were 24,000 men working on the Panama Canal. By 1911 there were approximately 45,000 workers. The workers who were contracted came from Panama and some from the United States, but also West Indian nations like Barbados, Europe, and Asia. By the end of 1905, 20 percent of the 17,000 canal workers were Barbadian because they were willing to work for cheaper wages.
