Economy - now a word taken to mean "the whole flow of money and goods and services in the world." Its origins are more humble, the first written use in English revealing a meaning more like "stewardship and management of a household." But because from that time in roughly the 1530s to now, the power of capital has taken hold as the dominant hegemony of the whole world, and because the conception of private property on which that power is built is based in Roman law, it's intrinsically based on the right of a paterfamilias to abuse and destroy his property and prevent the use or fruits of it to anyone else. Property which Roman law conceived to include land, household objects, the man's wife and children, and slaves. Slaves who the overall cultural perception of propriety thought ought to be war captives, but over time more and more came to be those who couldn't get out of debt any other way. Thus, the notion of management of a household came to be applied as a principle of managing society as a whole, "political economy."
