In this provocative new study, Zak Cope makes the case that capitalism is empirically inseparable from imperialism, historically and today. Using a rigorous political economic framework, he lays bare the vast ongoing transfer of wealth from the poorest to the richest countries through the mechanisms of monopoly rent, unequal exchange, and colonial tribute. The result is a polarized international class structure with a relatively rich Global North and an impoverished, exploited Global South.             Cope makes the controversial claim that it is because of these conditions that workers in rich countries benefit from higher incomes and welfare systems with public health, education, pensions, and social security. As a result, the internationalism of populations in the Global North is weakened and transnational solidarity is compromised. The only way forward, Cope argues is through a renewed anti-imperialist politics rooted in a firm commitment to a radical labor internationalism.
