There are several aspects of the current job situation that people are not talking about it seems. I will hit some of them for you.
First, machines have been putting people out of work since John Ludd warned about the first mechanical weaving machine in England back in the late 1700s. Particularly machines used outdoors for excavation, construction, farming, timber harvest, and indoors on assembly lines. Over the last ten years or more these indoor machines are being run by computers to make everything from small consumer goods to cars and trucks. And now computers (GPS and auto-steer) are showing up on farming equipment (tractors, combines, spraying equipment) that may displace the human operator. This trend will continue to displace human laborers, particularly since machines run by computers are building the robots that are displacing humans on automotive assembly lines and other places!
