Following independence and decolonization in the 20th century, most developing countries had dire need of new infrastructure, industry and economic stimulation. Many relied on foreign investment. This funding focused on improving infrastructure and industry, but led to a system of systemic exploitation. They exported raw materials, such as rubber, for a bargain. Companies based in the Western world have often used the cheaper labor in developing countries for production. The West benefited significantly from this system, but left developing countries undeveloped.
