Given the trends of globalization, automation and demographics, there will definitely be a small number of people who will be very prosperous. The challenge is to let as many people into that class as possible, and even more important, get masses of people educated to a level where they can qualify for work in the new businesses these people create. Throw in robotics, 3-D printing, and faster telecommunications, and things get tougher for the average worker. Robots may hollow out the factories in China, which count on cheap human labor, and bring manufacturing back to the United States. Those machines will need people to service them, and those people will need to be reasonably skilled. The way to combat it is education, which has to work for everyone, regardless of race or gender. You’ll have global competition for all kinds of jobs.
