If things ever got so bad that our money became virtually worthless, it might be possible to use poetry as a medium of exchange.
The better the poem, the greater the value.
A Pablo Neruda or David Ignatow would be worth something like fifty dollars, whereas a Rod McKuen might buy you a candy bar. Maybe.
Richard Brautigans would buy plenty, as well, but make you question why you were buying it at all.
A Bukowski poem would be worth thousands, but looked upon as foreign currency.
Of course, with the current rate of inflation, one would need more and more Nerudas and Ignatows just to get by, and eventually a loaf of bread might cost as much as a short story.
To buy a car, one would need to come up with two or three novels...good novels...a couple of Haruki Murakamis.
It would take a wallet full of Raymond Carver stories just to buy a motorcycle.
