You really think when we actually have the power to automate all labour the 1% are still going to be able to hoard all the resources? Now, when people have to work to live, it dissuades them from protesting the system. But once all labour is actually automated, there would be nothing to prevent the 99% from rightfully rising up against the 1% trying to hoard all the resources (which the 1% generated without any effort) and forcing societal/structural change.
