Power imbalances in global supply chains are used by multinational corporations to squeeze suppliers, and by suppliers to squeeze workers. Yet, supply chains involve far more than buyers, suppliers, and factory workers. Above buyers sit a range of financial sector actors demanding ever increasing returns on their investments, and above them are powerful states and inter-state institutions setting the rules of the game. In the past several decades, those rules have encouraged the proliferation of global supply chains through trade liberalisation and other policies.
