"The huge portion of our lives that we spend asleep, freed from a morass of simulated needs, subsists as one of the great human affronts to the voraciousness of contemporary capitalism. Sleep is an uncompromising interruption of the theft of time from us by capitalism. Most of the seemingly irreducible necessities of human life—hunger, thirst, sexual desire, and recently the need for friendship—have been remade into commodified or financialized forms. Sleep poses the idea of a human need and interval of time that cannot be colonized and harnessed to a massive engine of profitability, and thus remains an incongruous anomaly and site of crisis in the global present. In spite of all the scientific research in this area, it frustrates and confounds any strategies to exploit or reshape it. The stunning, inconceivable reality is that nothing of value can be extracted from it."
