7. A note on Wealth and Labor from Adam Smith (reference Reading Packet) “Every man is rich or poor according to the degree in which he can afford to enjoy the necessities, conveniences, and amusements of human life.” Our own labor can only do so much for us; we need others’ labor to bring us the joys of life.

8. Wealth is determined by how much labor we command, either our own labor or others The value of any commodity is equal to the quantity of labor which is required to possess it.

9. The “REAL” Price “The real price of every thing, what every thing really costs to the man who wants to acquire it, is the toil and trouble of acquiring it.” What we buy with money, we are really buying with our labor “Labor was the first price, the original purchase-money that was paid for all things. It was not by gold or silver, but by labor, that all the wealth of the world was originally purchased;”

10. Using labor to measure prices Gold, silver and money always have varying values. One cannot use a commodity to measure another commodity if the values are continually changing. However, equal quantities of labor are of equal value to the laborer. The price paid (labor) is always the same. Labor is alone the ultimate and real standard by which the value of all commodities can be compared. Labor is the real price, money is their nominal price only.

11. Measuring Labor Although labor should be the real measure of the value of all commodities, it is difficult to ascertain between two different sorts of work. The market sets the value of the different labors by bargaining.
