Millennials have been accused of ruining everything from dinner dates to golf. While it may be laughable to consider their influence on things like napkins and mayonnaise, what is absolutely true is that this largest living adult generation is shifting the economy towards one based more on sharing than consuming. Because of this shift, services are a more significant component of the global economy, having increased more than 200 percent in the last 20 years. Now more than 46 percent of the US gross domestic product (GDP) comes from services, outperforming not only goods, but also business investments, government spending and net exports. And the importance of services to the economy is only projected to further increase.
