It doesn't take a magic machine. Brilliant and succinct from Williamson: The Social Machine - Jobs are a means, not an end. A quote:
The people who have an explicit legal obligation to work not on our behalf but on behalf of their shareholders do a pretty good job of giving us what we want; the people who vow to work on our behalf do not. That is a paradox only if you do not think about it too much, and not thinking about it too much is the business that politicians are in.
If capitalism – which is to say, human ingenuity set free to follow its own natural course – is a kind of social machine, then politicians are something like children who take apart complex machines without understanding what they do or how to put them back together. (At their worst, they are simply saboteurs.) When they rail against capitalism, automation, trade, and the like, they resemble nothing so much as those hominids at the beginning of 2001: A Space Odyssey, shrieking hysterically at something that is simply beyond their comprehension.
Of course, most politicians really do know better. They are just bullshitting people, which is their mission if they want to keep their easy job.
