How do you make money?

The "Make Money Fast" chain letter encouraged readers of the email to forward one dollar in cash to a list of people provided in the text, and to add their own name and address to the bottom of the list after deleting the name and address at the top. Using the theory behind pyramid schemes, the resulting chain of money flowing back and forth would supposedly deliver a reward of thousands of dollars to the ones participating in the chain, as copies of their chain spread and more and more people sent one dollar to their address.
