The ultimate, hidden truth of the world is that it is something that we make, and could just as easily make differently. - David Graeber

Before we can apply the tools of anthropology to reconstruct the real history of money, we need to understand what's wrong with the conventional account.

Karl Marx, who knew quite a bit about the human tendency to fall down and worship our own creations, wrote Das Capital in an attempt to demonstrate that, even if we start from the economists' utopian vision, so long as we also allow some people to control productive capital, and, again, leave others with nothing to sell but but their brains and bodies, the results will be in very many ways barely distinguishable from slavery, and the whole system will eventually destroy itself.

Say what you like about nurses, garbage collectors, or mechanics, it's obvious that were they to vanish in a puff of smoke, the results would be immediate and catastrophic. A world without teachers or dock-workers would soon be in trouble, and even one without science fiction writers or ska musicians would clearly be a lesser place. It's not entirely clear how humanity would suffer were all private equity CEOs, lobbyists, PR researchers, actuaries, telemarketers, bailiffs or legal consultants to similarly vanish. (Many suspect it might markedly improve.) Yet apart from a handful of well-touted exceptions (doctors), the rule holds surprisingly well.
