“在进步的社会中，财富的集中可能会达到一个临界点，穷人人多势众，与少数富人的能力优势相抗衡；然后，这种不稳定的平衡引发了一种临界状态。历史上对此曾有两种截然不同的回应：要么通过立法重新分配财富；要么通过革命分配贫困。”
—— 威尔·杜兰特，《历史的教训》

“In progressive societies the concentration [of wealth] may reach a point where the strength of number in the many poor rivals the strength of ability in the few rich; then the unstable equilibrium generates a critical situation, which history has diversely met by legislation redistributing wealth or by revolution distributing poverty.”
― Will Durant, The Lessons of History
