I don't necessarily disagree with this, but I have to ask - how do you ration goods and services in an economy except for some kind of currency? And how do you propose we award people said currency besides some direct or indirect correlation with their work output? It seems likely to me that technology will continue to create a gap between the supply of workers and the demand for those workers, but figuring out how to deal with the social and economic implications of that seems like a difficult task.
