The reality is that globalization has two sides. The first and more obvious one is the geographic spread of routine economic functions such as simple manufacturing or service work (for example, making or answering telephone calls). The second, less obvious side to globalization is the tendency for higher-level economic activities such as innovation, design, finance, and media to cluster in a relatively small number of locations.
The world gets spikier and spikier the further you climb up the ladder of economic development, from producing basic goods to undertaking significant new innovations.
