If you're a poorly educated westerner, there isn't much for you to do even now. OECD countries all complain about households in which nobody has ever worked. Given the falling relative and absolute standards of education, it's hard to see opportunities for them.
To my mind, automation and low wages elsewhere in the world have had a big impact on the labour pool. This may be difficult for highly employable folk reading this board to grasp, but consider what folk are doing as they leave college. Sure, lots of them are getting well-paid jobs, but a heck of a lot are interning and struggling along with 10-dollar jobs on the freelance auction sites.
But why is there a general panic when the possibility of the end of work arises? For billions of people it would mean freedom from drudgery and the prospect of doing more fulfilling things instead - looking after families, creating things, learning new stuff and so on.
