We must rapidly begin the shift from a "thing-oriented" society to a "person-oriented" society. When machines and computers, profit motives and property rights are considered more important than people, the giant triplets of racism, materialism, and militarism are incapable of being conquered.
Martin Luther King, Jr.

Our life on earth is, and ought to be, material and carnal. But we have not yet learned to manage our materialism and carnality properly; they are still entangled with the desire for ownership.
Edward M. Forster

For greed, all nature is too little.
Seneca

It is the bread of the hungry you are hoarding, the clothes of the naked that hang in your wardrobe, the shoes of those who go barefoot that fall to pieces in your house, the money of the poor that you possess and do not use. You commit as many injustices as there are things you could give away.
St. Basil the Great

Earth provides enough to satisfy every man's need, but not every man's greed.
Mahatma Gandhi

The gap in our economy is between what we have and what we think we ought to have – and that is a moral problem, not an economic one.
Paul Heyne
