I agree with you in the sense that's how they rationalize their reaction, although I think they don't actually wonder about it and you made a figure of speech, and instead they don't feel it's fair that some stop working until everything is completely automated.

But I see an inconsistency in their feeling of injustice, because some people have to work a lot to get comparatively very little benefits from our largely automated economy. Anyone who works should feel like they live a luxurious life. Instead we see a lot of addiction and despair, despite lifestyles that consume huge amounts of energy.
