The natural price, therefore, is, as it were, the central price, to which the prices of all commodities are continually gravitating.
Adam SmithThe natural effort of every individual to better his own condition is so powerful that it is alone, and without any assistance, capable not only of carrying on the society to wealth and prosperity, but of surmounting 100 impertinent obstructions with which the folly of human laws too often encumbers its operations.
Adam SmithThe principle which prompts to save is the desire of bettering our conditiona desire which?comes with us from the womb and never leaves us till we go into the grave.
Adam Smith
