The relationship between Aristotle’s position on the ‘nature’ of money based exchange and later judgment

1) Explain the relationship between Aristotle’s position on the ‘nature’ of money based exchange and later judgments that interest taking is anti-social (evil).

2) Using von Hornick’s defense of Mercantilism, how do you view the economic problem of a typical modern (eg. Brazil) country?
