Every bar of chocolate, T-shirt, and smartphone battery has a backstory. Some of that story is about value moving in one direction, and cost moving in another.
Subtopic 7.3 examines how global exchange systematically transfers economic value from the Global South to the Global North, while shifting ecological and physical costs the other way. You will trace this pattern through unequal prices and wages, through the labour of migrants who leave home to care for other people's families or build other countries' cities, and through pollution, waste, and resource extraction that fall disproportionately on communities with the least power to refuse them. You will also examine the physical and financial chokepoints, from shipping straits to the dominance of the US dollar, that let a small number of actors control global exchange. You will look at how debt, aid, and the stories told about "development" often reinforce these imbalances rather than resolve them.
This is not a simple story of villains and victims. Powerful firms, states, and institutions actively shape these relationships and benefit most from them. But most people caught up in this system, on both sides, are working within constraints they did not choose. These patterns are not universal or unchanging either. They play out differently across countries and regions, and some countries have pushed back against them. Understanding these patterns matters because they show where the leverage points for change might be.
At the end of Subtopic 7.3 you should be able to:
explain how unequal prices and unequal wages systematically transfer value from Global South countries to Global North countries
identify the structural barriers that prevent Global South countries from moving into higher-value production
describe the push and pull factors that drive migration between sending and receiving countries
identify the power relationships and structural conditions that shape labour migration and the work that labour migrants do
evaluate the benefits and drawbacks of labour migration for individual migrants, sending countries, and receiving economies
discuss how the global economy systematically transfers ecological costs from Global North to Global South countries, using evidence from pollution and waste, resource depletion, and climate change
describe the main physical chokepoints in global exchange systems, including maritime routes, energy infrastructure, and digital cables
explain why disruptions to physical chokepoints have unequal consequences for different countries and communities
explain how the global economy has created concentration chokepoints in critical minerals, technology, digital infrastructure, and financial systems
explain how physical and concentration chokepoints together amplify systemic risk and reinforce existing inequalities between countries
explain how US dollar dominance shapes the global financial system, and is leveraged in global exchanges
explain how borrowing in foreign currencies creates vulnerabilities for countries in the periphery
describe how debt servicing, illicit financial flows and repatriated profits transfer wealth from periphery to core countries
explain why debt crises are difficult to resolve and who has power in restructuring negotiations
explain how development aid can affect the sovereignty, institutions, and debt of receiving countries
discuss the extent to which development aid serves recipient countries and/or donor countries
explain why economic decisions, such as government budgets, aid agreements, and tax systems, shape whether peace holds after a war ends
distinguish between the drivers of conflict between states and the drivers of conflict within states
explain how development narratives function to maintain existing patterns of global exchange
