“‘Money talks’ because money is a metaphor, a transfer, and a bridge. Like words and language, money is a storehouse of communally achieved work, skill and experience… money is a language for translating the work of the farmer into the work of the barber, doctor, engineer, or plumber” (McLuhan, 1964).
There are many metaphors for money. We talk about money and related financial concepts as solids (eroding capital, cutting budgets), liquid (pooling assets, pouring money into an investment, the farce of trickle-down economics), and even gas (inflation). But McLuhan suggests that money itself is a metaphor – for example, for work.
