Final answer:
The core/periphery dynamic refers to the unequal distribution of power and economic development, where some regions lag behind and form the periphery to a more powerful core. Core areas attract resources, wealth, and skilled people, resulting in a concentration of economic activity and brain drain from the periphery.
Step-by-step explanation:
The situation described in the question is known as the core/periphery dynamic. The core/periphery dynamic refers to the unequal distribution of power and economic development, where certain regions that are more powerful and prosperous act as the core, while other regions that lag behind form the periphery. The core areas attract resources, wealth, and skilled people from the periphery, resulting in a concentration of economic activity and opportunities in the core. This dynamic is also associated with brain drain, where educated individuals from the periphery often migrate to the core for better employment prospects.
