A society that is characterized predominantly by production directly for use is a bit different than a society characterized predominantly by production for exchange. In a society where production is directly for the use of the product, a good or commodity is only worth whatever its use-value is. This means that a product's worth is based solely on its use to the person using it. A good example of this system would be feudalism in which a serf would be able to produce enough for his own needs and then sell the surplus product in order to buy other useful products that he himself cannot produce. In a society that uses production for exchange a product is only worth whatever it's exchange-value is. Exchange-value is based on the labor time "socially necessary" for the production of the particular commodity, and is the main measure that determines rates of exchange and thus the logic of commodity production. Capitalism is the main example of this type of social production, a capitalist will use "capital" to invest in goods or commodities in order to gain a profit by exploiting laborers.
             In a society characterized by simple commodity production there are many differences from a society characterized by capitalistic production.

In a society characterized by capitalistic production, a person starts out with money with which he buys commodities (labor, goods, etc.) in order to get more money. The capitalist will generally invest in commodities such as buildings, tools, and workers. If you consider the case of your average bread-maker, the difference in the two societies becomes easier to see. In the case of simple commodity production the bread-maker will be able to ...
