The worldview of populist politicians has been in the ascendancy, characterised by isolationism, protectionism and nationalism. The path to prosperity, they argue, is one where economies are closed. Trade is restricted. Markets are managed. Foreign investment is blocked. Immigrants are expelled. Economic co-operation is for the weak.
The protectionist, isolationist economic model of the populists has been nothing short of a catastrophic failure, associated with a collapse of global confidence and investment that threatens global jobs and growth. Global GDP growth is falling, trade growth has halved since 2017, foreign investment has fallen by almost a third since 2017 and supply chains are unravelling at dangerous speed, threatening a sharp rise in production costs and a sharp fall in already anaemic productivity growth.
