As crises económicas não são uma coisa nova. Este pequeno instante de uma das obras de Aristóteles dá-nos a entender isso mesmo:
There was a man of Sicily, who, having money deposited with him, bought up an the iron from the iron mines; afterwards, when the merchants from their various markets came to buy, he was the only seller, and without much increasing the price he gained 200 per cent. Which when Dionysius heard, he told him that he might take away his money, but that he must not remain at Syracuse, for he thought that the man had discovered a way of making money which was injurious to the interests of the god. He made the same discovery as Thales; they both contrived to create a monopoly for themselves.
