We are underpowered because our economy for the last 30 years has been suffering a productivity disease. Economic growth has largely been driven by having more people in the country and more people working harder. We need to work smarter, not harder. We can do this, and we can do it by building and unleashing genuinely world-class export businesses, step-changing education and labour skills, and delivering infrastructure better. Improving productivity is the single biggest thing that we can do to raise our collective standard of living.
