I don't know if those two statements you used are isomorphisms. I haven't read the book that the title is making reference to, 24/7: Late Capitalism and the Ends of Sleep, but I'd guess that they are not trying to anthropomorphize capitalism, but more using the term as synecdoche in referring to the interests of the collection of decision makers who benefit the most from capitalism -- at the cost of all the externalities of living in a capitalist society, in this case the amount of sleep the average member of the proletariat gets, but also environmental costs, the interests of the weak and the oppressed, and any other harm that doesn't lend itself to be easily measured in terms of financial gain or loss.
