The secret of money:

Let’s say the world consists of only four people: Adele π΅, Berta π©π»βπ, Chris π¨ββοΈ and Desmond π€. Since it is a fair world, every single one has equally earned a fortune of β¬ 10,- up to now.

Additionally, Adele inherited a brandnew car from her parents, Berta studied business and has become a saleswoman, Chris started to work as a Taxi driver, and Desmond meanwhile owns a bank.

π΅: β¬ 10,- plus π

π©π»βπ: β¬ 10,-

π¨ββοΈ: β¬ 10,-

π€: β¬ 10,-

(Situation X 01 – see footnote)

Now Berta buys the car from Adele for β¬ 10,- (X 02) to sell it to Chris profitable for β¬ 15,- (X 03). Thus Chris has to borrow β¬ 5,- from Desmond to buy it (X 04). Desmond lends it to Chris on the condition that he will get back β¬ 10,- in four years. It’s the year 2011:

2011:

π΅: β¬ 20,-

π©π»βπ: β¬ 15,-

π¨ββοΈ: β¬ 0,- plus π

π€: β¬ 5,-

Within these four years, Chris provides driving services for Berta, earning β¬ 10,- (X 05). He then pays back β¬ 10,- to Desmond (X 06). Finally, Chris sells the used car to Adele for β¬ 10,- (X 07). So Adele again owns β¬ 10,- and a used car, Berta owns just β¬ 5,-, Chris still β¬ 10,- and Desmond already β¬ 15,-.

2015:

π΅: β¬ 10,- plus π

π©π»βπ: β¬ 5,-

π¨ββοΈ: β¬ 10,-

π€: β¬ 15,-

During the next four years Adele sells the used car to Berta without profit for β¬ 10,- (X 08). So Berta has to borrow β¬ 5,- from Desmond (X 09) and will also return him β¬ 10,- after four years. She has to earn this money by reselling the used car to Chris for β¬ 10,- (X 10). After the repayment she is broke (X 11). Finally Chris sells the car without having used it back to Adele for the original price of β¬ 10,- (X 12).

2019:

π΅: β¬ 10,- plus π

π©π»βπ: β¬ 0,-

π¨ββοΈ: β¬ 10,-

π€: β¬ 20,-

What happened in those eight years?

π΅ Adele is just as wealthy as before

* but her car is now a used one.

π©π»βπ Berta has consumed her β¬ 10,- and earned β¬ 5,- by trading

* and is already broke.

π¨ββοΈ Chris has worked for β¬ 10,- and used only β¬ 5,-

* but is still not richer than before.

And Desmond?

π€ Desmond did not work at all

* and yet has doubled his wealth.

Everything works like clockwork.

Do you have a banking license for me?
