Xenophon 
On Revenues [PDF ebook] 

Xenophon the Athenian was born 431 B.C. He was a pupil of Socrates. He marched with the Spartans, and was exiled from Athens. Sparta gave him land and property in Scillus, where he lived for many years before having to move once more, to settle in Corinth. He died in 354 B.C.
Revenues describes Xenophon’s ideas to solve the problem of poverty in Athens, and thus remove an excuse to mistreat the Athenian allies.
