"The proposition, LABOR IS THE PRINCIPLE OF PROPORTIONALITY OF VALUES, not only is true, resulting as it does from an irrefutable analysis, but it is the object of progress, the condition and form of social well-being, the beginning and end of political economy. From this proposition and its corollaries, EVERY PRODUCT IS WORTH WHAT IT COSTS, and PRODUCTS ARE BOUGHT WITH PRODUCTs, follows the dogma of equality of conditions. "The idea of value socially constituted, or of proportionality of values, serves to explain further: (a) how a mechanical invention, notwithstanding the privilege which it temporarily creates and the disturbances which it occasions, always produces in the end a general amelioration; (b) how the value of an economical process to its discoverer can never equal the profit which it realizes for society; (c) how, by a series of oscillations between supply and demand, the value of every product constantly seeks a level with cost and with the needs of consumption, and consequently tends to establish itself in a fixed and positive manner; (d) how, collective production continually increasing the amount of consumable things, and the day's work constantly obtaining higher and higher pay, labor must leave an excess for each producer; (e) how the amount of work to be done, instead of being diminished by industrial progress, ever increases in both quantity and quality--that is, in intensity and difficulty--in all branches of industry; (f) how social value continually eliminates fictitious values,--in other words, how industry effects the socialization of capital and property; (g) finally, how the distribution of products, growing in regularity with the strength of the mutual guarantee resulting from the constitution of value, pushes society onward to equality of conditions and fortunes. "Finally, the theory of the successive constitution of all commercial values implying the infinite progress of labor, wealth, and well-being, the object of society, from the economic point of view, is revealed to us: TO PRODUCE INCESSANTLY, WITH THEE LEAST POSSIBLE AMOUNT OF LABOR FOR EACH PRODUCT, THE GREATEST POSSIBLE QUANTITY AND VARIETY OF VALUES, IN SUCH A WAY AS TO REALIZE, FOR EACH INDIVIDUAL, THE GREATEST AMOUNT OF PHYSICAL, MORAL, AND INTELLECTUAL WELL-BEING, AND, FOR THE RACE, THE HIGHEST PERFECTION AND INFINITE GLORY.
