Which theory suggests that modernization and development will gradually improve the lives of people in peripheral nations?

Modernization theory posits that as societies progress through various stages of development, they will eventually experience improvements in living standards, economic growth, and overall quality of life. This theory emphasizes that peripheral or developing nations can achieve the same level of economic and social development as industrialized countries by adopting modern technologies, practices, and institutions.

Proponents of modernization theory often argue that external support, investment, and the transfer of knowledge from developed nations can lead to positive changes in peripheral nations. The idea is that through processes such as industrialization, urbanization, and education, these nations can transition away from traditional societal structures and practices towards more modern economic systems.

This theory is grounded in the belief that development is a linear process and that all societies follow a similar trajectory towards modernization, ultimately leading to improved living conditions.
