It was natural that with the maturing of an American population, the exploitation of the natural resources should come. We have exploited the forest, removing the timber from the hills and making out of its vast resources a few fortunes. We wasted in the process nine-tenths for every one-tenth of wealth accumulated by the exploiter. We have exploited the coal and iron and other minerals. The exploitation of the oil deposits and natural gas reservoirs has been a national experience and a national scandal. The tendency to exploit every opportunity for private wealth has characterized the past two decades.[7] There are those who exploit the child vitality of the families of working people, and the States have put legal checks in the way of child labor. The exploitation of the labor of women has gone so far as to threaten the vitality of the generation to be born, and laws have been passed which forbid the employment of women except within limits. The ethical discussion of the past decade is largely a keen analysis of the methods of exploitation of resources, of men and of communities, and an attempt to fix the bounds of the exploitation of values for private wealth. There are those who exploit the farm. "Farms which from the original entry until 1890 had been owned by the same family, or which had changed owners but once or twice, and whose owners were proud to assert that their broad acres had never been encumbered with mortgages, since 1890 have been sold, in some instances as often as ten times, in more numerous instances four or five times, and a large part of the purchase price is secured by encumbering the estates!"[8] Agriculture, especially of the Middle West, is affected in all its parts by the exploitation of land. To a traveller from the Eastern States, the selling and re-selling of farm land, without fertilization or improvement by any of the successive owners, is a source of amazement. "The new lands opened under the Homestead act of half a century ago were often exploited for temporary profit by soil robbers who were experts of their kind. Owing to such farm management, the yield of the acre in the United States gradually decreased. Very little intensive farming was done."[9]
