“The upper classes among the ancients never had intelligence or ability enough to direct the poor towards labor, and thus help them to escape honorably from their misery and corruption. A few benevolent men attempted it, but they did not succeed. The result was that the cities always floated between two revolutions, one to despoil the rich, the other to enable them to recover their fortunes. This lasted from the Peloponnesian war to the conquest of Greece by the Romans.”
