People with access to technology can work remotely although I think offices are better because they're conducive for knowledge spillovers. I could be wrong, however.
I can definitely see some folks working remotely. It makes sense for a lot of people.
Young people can learn new skills if they have access to the internet, and the desire. edX, Coursera, GitHub, YouTube (to name a few) are brilliant if you know where to look for the right things. Formal education, although preferable, doesn't matter as much as it used to. Universities are hosting online courses, some of them for free; MIT OpenCourseware comes to mind. The world is only a few clicks away.
