§ 5. American economic problems in the past. What, then, are the politico-economic problems in America? They are problems that are economic in nature because they concern the way that wealth shall be used and that citizens are enabled to make a living, but that are likewise political because they can be solved only collectively by political action. With, the first settlements of colonists on this continent politico-economic problems appeared. Take, for example, the land policy. Each group of colonists and each proprietary landholder had to adopt some method of land tenure, whether by free grant or by sale of separate holdings or by leasing to settlers. In one way and another these questions were answered; but rapidly changing conditions soon forced upon men the reconsideration of the problem as the old solution ceased to be satisfactory.

In large part our political history is but the reflection of the economic motives and economic changes in the national life. Thus the American Revolution arose out of resistance to England's trade regulations, commercial restrictions, and attempted taxation of the colonies. The War of 1812 was brought on by interference with American commerce on the high seas. The Mexican War was the result of the colonization of Texas territory by American settlers and the desire of powerful interests to extend the area of land open to slavery. The Civil War arose more immediately out of a difference of opinion as to the rights of states to be supreme in certain fields of legislation, but back of this political issue was the economic problem of slave labor. Illustrations of this kind, which may be indefinitely multiplied, do not prove that the material, economic changes are the cause of all other changes, political, scientific, and ethical; for in many cases the economic changes themselves appear to be the results of changes of the other kinds. There is a constant action and reaction between economic forces and other forces and interests in human society, and the needs of economic adjustment are constantly changing in nature.

§ 6. Main factors in economic problems. The particular economic problems in America at this time are determined by the whole complex economic and social situation. Two main factors in this may be distinguished: the objective and the subjective, or the material environment and the people composing the nation. The one is what we have, the other is what we are. These factors are closely related: for what we are as a people (our tastes, interests, capacities, achievements) depends largely on what we have, and what we have (our wealth and incomes) depends largely on what we are.

I.  The objective factor presents two phases:

(a)   The basic material resources, consisting of the materials of the earth's surface and the natural climatic conditions which together provide the physical conditions necessary for human existence, and which furnish the stuff out of which men can create new forms of wealth.

(b)   The industrial equipment, consisting of all those artificial adaptations and improvements of the original resources by which men fit nature better to do their will. These two (a and b) become more and more difficult to distinguish in settled and civilized communities, and become blended into one mass of valuable objects, the wealth of the nation.

II.  The subjective factor presents two phases:

(a)   The people, considered with reference to their number, race, intelligence, education, and moral, political, and economic capacity.

(b)   The social system under which men live together, make use of wealth and of their own services, and exchange economic goods.

The particular economic problems that are presented to each generation of people are the resultant of all these factors taken together. A change in any one of them alters to some extent the nature of the problem. The problems change, for example, (1 a) with the discovery or the exhaustion (or the increase or decrease) of any kind of basic material resources; (1 b) with the multiplication or the improvement of tools and machinery or the invention of better industrial equipment; (II a) with the increase or decrease of the total number of people, and the consequent shift in the relation of population to resources; (II b) with changes in the ideals, education, and capacities of any portion of the people whether or not due to changes in the race composition of the population.

Many examples of these various changes may be found in American history, and some knowledge of them is necessary for an appreciation of the genesis and true relation of our present-day problems.

§ 7. Range of economic problems treated. Of numberless economic problems that are calling for solution in a modern nation like the United States of America, only the more important in relation to present needs can be discussed in their main aspects within the limits of a single volume. The ones here chosen, as may be seen by referring to the table of contents, include a wide range, from the more impersonal financial questions connected with money and the medium of exchange, to the most burning issues of class interests and conflicts; and from those that seem to do merely with the individual (as incomes or wages or taxes) to the most fundamental questions of the form of economic organization and the displacement of private property by communism. In truth, these contrasts are often misleading; for the welfare of individuals is affected in many ways, often remote and unsuspected, on the one hand by impersonal factors such as the production of gold or the invention of machinery, and on the other hand by the form and function of the social organization of which each of us is a part.

Some conceive of the economist's task narrowly as being merely the study of market prices; others broaden the field to include the study of individual valuations and gratifications; and still others make it include the solution of all problems of economic legislation affecting the general welfare of society. No practical problem in the field of economics can be rightly solved as if it were an economic problem in any narrow sense untouched by political, moral, and social considerations. In this volume the broadest of these conceptions is taken, prices and values being studied because of their bearing upon social welfare. Welfare economics rather than price economics is our ideal.
