The accumulation of gold in the treasury of private individuals is the ruin of timocracy; they invent illegal modes of expenditure; for what do they or their wives care about the law?
And then one, seeing another grow rich, seeks to rival him, and thus the great mass of the citizens become lovers of money.
And so they grow richer and richer, and the more they think of making a fortune the less they think of virtue; for when riches and virtue are placed together in the scales of the balance, the one always rises as the other falls.
And in proportion as riches and rich men are honoured in the State, virtue and the virtuous are dishonoured.
And what is honoured is cultivated, and that which has no honour is neglected.
– – Plato’s Republic Book VIII
