Even though I mostly agree with the conclusion of this article, it is a pretty bad take otherwise. They even partially contradict themselves and in general seem to think that there is no such thing as an equilibrium, but only boom or bust (and yes reaching and maintaining an equilibrium is hard work).
If I had time and motivation I would write an parody on this article from the view of the late Roman empire where a person complains about how society can not survive without slave labor and how everything is build on it and so on. Yes, the Roman empire did eventually collapse, but not because of a lack of cheap slave labor.
