US president Joe Biden is making infrastructure spending a government priority, as his $1.7tn American Jobs Plan demonstrates.
According to economists, investment in repairing and modernising physical infrastructure (such as roads, bridges, and water and energy systems) and human capital spending (or instance in education and training) have all declined continuously since the 1960s, to reach only between 1% and 2% of US gross domestic product (GDP) in recent years.
