I may read too much sci-fi, but I am fully convinced that we are heading to a future where most menial, low skill tasks will soon be done by technology and robotics. We have been heading in that direction for quite some time and I don't see that changing. The end result is the near elimination of low skill jobs. This doesn't necessarily mean that people won't be able to find work, it's just that we will need to do a better job at educating them to prepare them for more high skilled labor.
