This paper examines the effects of globalization on nations, focusing on economic, social, and cultural dimensions. It analyzes the roles of protectionism and globalization in shaping consumer welfare and producer earnings through qualitative methods and the Customs Union theory framework. The study discusses the benefits and drawbacks of globalization in the context of World Trade Organization (WTO) regulations. The findings indicate that globalization has intensified financial flows between countries, which can exacerbate economic crises. Countries with abundant human resources can capitalize on the international division of labor to specialize in high-value sectors, while those with limited resources risk falling behind in the digital landscape. This division of labor fosters specialization and improves production efficiency through targeted education. However, multinational corporations often impede cost-effective production in developing nations, underscoring the necessity to restructure research and development to facilitate technology adoption in underdeveloped areas. This restructuring can help close the technological gap and encourage equitable participation in the global economy.
