 According to Immanuel Wallerstein, one of the most well-known theorists who developed the world-systems approach, a core nation is dominant over the non-core nations from its economic and trade dominance.The abundance of cheap and unskilled labour in the peripheral nations makes many large multinational corporations (MNCs), from core countries, often outsource their production to the peripheral countries to cut costs, by employing cheap labour.Hence, the languages from the core countries could penetrate into the peripheries from the setting up of the foreign MNCs in the peripheries.
