Book excerpt: World-renowned economist Vijay V. Vaitheeswaran provides a deeply insightful, brilliantly informed guide to the innovation revolution now transforming the world. With echoes of Clayton Christensen’s The Innovator’s Dilemma, Tim Brown’s Change by Design, and Jared Diamond’s Guns, Germs, and Steel, Vaitheeswaran’s Need, Speed, and Greed introduces readers to the go-getters, imagineers, and visionaries now reshaping the global economy. Along the way, Vaitheeswaran teaches readers the skills they must develop to unleash their own inner innovator and reveals why America and other wealthy, privileged societies must embrace a path of inclusive growth and sustainability—or risk being left behind by history.
