One day a tourist comes to the only hotel in a debt ridden town in Kenya. He lays a 100 dollar note on the table and goes to inspect the rooms. Hotel owner takes the note and rushes to pay his debt to the butcher. Butcher runs to pay the pig farmer. Pig farmer runs to pay the feed supplier. Supplier runs to pay the prostitute, who in these hard times gave her services on credit.
Prostitute then runs to pay off her debt to the owner for the rooms she rented for her clients. Hotel owner then lays the 100 dollar note back on the counter. The tourist comes down, takes his money and leaves as he did not like the rooms.
No one earned anything. But that group of people is now without debt and looks to the future with a lot of optimism.
And that is how the world is doing business today!
