There's little to no relation between the technology used in Inception (the dream-entering/'extraction' device) and automation of human labor, however it’s use for extraction of ideas/knowledge from peoples’ minds could contribute to global corporate espionage, as well as the implantation of ideas into key business figures’ heads, just as the movie’s plot demonstrates: implanting the idea into Fischer that rather than taking up his father’s mantle and continuing to lead his company, he should instead dissolve the company entirely.
