There are a great many other occupations in the list[4] from which these items are taken which might properly be included in the above, as the combination which does or can exist in them it is almost certain is of no practical importance. On the other hand, however, our total of 5,647,368 takes no account of the persons interested in trade, transportation, or manufacturing through holding the shares or bonds of incorporated companies; also the errors and omissions of the census are so great in any event that only broad and general statements can be based upon them. Deducting, then, from the total of 5,647,368 the 1,632,000, which we found to be surely not interested in monopolies, we have about four million persons as the utmost number who are benefited by the profits of the monopolies which we have thus far considered. But let us look into this a little farther. As we have already stated, the monopolies of trade are generally unable to raise prices far above their normal rate. In retail trade, especially, competition shows great tenacity of life. Also with regard to labor monopolies, it is true, as we have already stated, that the limits of their operation are pretty closely defined; even the men in the highest grades of skilled labor cannot secure for each workman by any combination more than two or three dollars per day over what he would receive under the freest competition. Let us, therefore, deduct from the preceding four millions the persons engaged in retail trade, and all skilled laborers in the various trades which we formerly included because we conceived that they might be connected with some form of labor organization, and might also obtain some benefit through the profits of their employers. But when we make these deductions we find that we have only a hundred thousand or so of our four millions left. Briefly summed up, therefore, the fact is, that the strong monopolies in manufacturing, mining, trade, and transportation are owned by a very small portion of the population. Just what this number is, it is impossible to say, for the stock and bonds of railroad companies, mining companies, and manufacturing companies are changing hands continually, and no public record is taken of their distribution and ownership. It may possibly be true, however, that one million different persons own an interest in some of the various monopolies which we have studied, excluding the monopolies in trade and labor. But even if this estimate is correct, it is a well-known fact that a few hundred immensely wealthy men hold a large share of the stock of these very profitable monopolies.
