In all the talk of “building back better” and making economies “match fit”, “strategically autonomous” and “resilient”, there is an unstated but tragic premise. For decades, most advanced economies did not build their future but languished in an investment drought, the scandal of which is greater for being unacknowledged.
Between 1970 and 1989, the share of gross domestic product devoted to investment by six of the world’s seven biggest economies averaged from 22.6 per cent for the US to 24.8 per cent for Germany. The seventh, Japan, was an outlier with 35 per cent.
Of the G7, only Canada has sustained this level of investment: its 22.5 per cent in this millennium is barely down from 22.8 back then. All the others have only managed to match their 1970-89 investment levels in four instances: the US in the boom years of 2000 and 2005-06, and France in 2021.
