land and labour of the country, the real wealth and revenue of all its inhabitants.
Capitals are increased by parsimony, and diminished by prodigality and misconduct.
Whatever a person saves from his revenue he adds to his capital, and either employs it himself in maintaining an additional number of productive hands, or enables some other person to do so, by lending it to him for an interest, that is, for a share of the profits. As the capital of an individual can be increased only by what he saves from his annual revenue or his annual gains, so the capital of a society, which is the same with that of all the individuals who compose it, can be increased only in the same manner.
Parsimony, and not industry, is the immediate cause of the increase of capital. Industry, indeed, provides the subject which parsimony accumulates; but whatever industry might acquire, if parsimony did not save and store up, the capital would never be the greater.
