Outside of a autocratic, centralized economy I would wager that it's natural for an economy to "find new work" for labor. The fact that we have increased automation does not mean that the labor force should shrink along with it, it should mean that over generations people do new things. An office supply company in the 70s would bet big on fax machines, with the ubiquity of email a comparable company today might focus on ergonomic office supplies.
