We realized that among us, among all the races, we had a staggering fund of knowledge and of techniques - that working together, by putting together all this knowledge and capability, we could arrive at something that would be far greater and more significant than any race, alone, could hope of accomplishing.

Money here on Earth is more than the paper or the metal that you use for money, more than the rows of figures that account for money. Here on Earth you have given money a symbolism such as no medium of exchange has anywhere else I have ever known or heard of. You have made it a power and a virtue and you have made the lack of it despicable and somehow even criminal. You measure men by money and you calibrate success with money and you almost worship money.
