What determines the value of your work and the value of your purchases, though?
There has to be a measure of belief in there somewhere I think.
If people don't believe that my work has value and I don't believe that the purchases that I could make (assuming someone thought my work had value so that I had credit to spend) have value, doesn't the whole deck of cards collapse about my ears?
Credit, we can remember, comes from credere to believe. (I believe).
