This is going to turn into an excuse to put a boot on the Valley's neck.
The reality is, there hasn't been a real labor intensive new thing in the past 30+ years. What new thing requires massive man power to do? Even programmers, our job go easier with time. A programmer today with tools today is much more productive then he used to be. Same for most professions.
Companies are outputting the same with less employees now. Productivity measures are up. That just means a more efficient society that requires more and more complex jobs that haven't yet been automated. Some people just can't do those jobs.
