A human trinity

“In every state there are three parts: the very rich, the very poor, and the middle class. So since it is agreed that the best and the mean is that which is moderate, it is evident that the best possession of goods which comes from fortune, too, is the one which is moderate, for this is the easiest to deal with in a rational manner; for he who greatly excels in beauty or strength or high birth or wealth, or in the contrarities of these, i.e. in ugliness or weakness or low birth or poverty, finds it difficult to follow reason. The former tend to become insolent or great criminals, but the latter rather rogues and petty rascals; for, of unjust effects, some result through insolence, others from roguery.” – Aristotle, Politics, Book IV (trans. Apostle and Gerson)
