From Plutarch’s Moralia:
When the Megarians had expelled Theagenes their tyrant, for a short time they were sober and sensible in their government (politeia). But later when the popular leaders (demagogoi) poured out untempered freedom for them, as Plato says, they were completely corrupted, and, among their shocking acts of misconduct toward the wealthy the poor would enter their homes and insist upon being entertained and banqueted sumptuously. But if they did not receive what they demanded, they would treat all the household with violence and insult (hubris). Finally, they enacted a decree whereby they received back again the interest that they happened to have paid their creditors, calling the measure “return interest”.
“Return interest.” I like that.
