“Even the richest person, provided the riches comes from mutually beneficial exchange, does not need to give anything "back" to the community, because this person took nothing out of the community.

Their riches are signs that they have achieved their aims.”

― Henry Hazlitt, Economics in One Lesson: The Shortest and Surest Way to Understand Basic Economics

“It is infinitely better to rely on the pursuit of economic interest by landowners or street companies than to depend on the dubious “altruism” of bureaucrats and government officials.”
