However, for this to be done effectively, changes will also be needed in global governance in order to provide sufficient space for national self-determination, while preserving coherence with shared global development objectives. Rooted in modern growth theory which dominated early development theory, development policies of the 1950s and 1960s focused on promoting modern industrial development to accelerate overall economic growth. Industrial growth was supported through trade protection, cheap credits and subsidies and large-scale public investments in infrastructure. Output growth was expected to “trickle down” to the entire population and reduce poverty through rising wages and employment generation, even if initially poverty reduction might not be commensurate with the rate of output growth, as rising income inequality was expected to be an inevitable, although temporary side effect of industrialization.
