We have now assumed for the purpose of comparison that the two cities, one of Mars and one of the Earth, have each three hundred thousand inhabitants; and that, allowing for women and children not engaged in productive industry, one hundred thousand of each city is actively engaged in industrial pursuits. As the general prosperity of each city depends upon the earnings of this one hundred thousand, and the accumulations in capital and wealth upon the amount saved by these productive classes, let us make a relative estimate of the opportunities each possess in individual savings. Having no common medium of exchange upon which to base our estimate, let us take the value of a day’s labor for that purpose. The income of a city is derived from two sources, the aggregate wages of its inhabitants, and the combined profits of its capital. The latter, however, being entirely derived from consumers, is largely contributed to by the inhabitants themselves. And for the reason that all imported products, as well as those exported, bear the profits of capital in their rates of sale, we may safely say that an amount very nearly equal to the whole profits of capital of a city is paid by the consumers within its limits as capital profits. The chief source of your city’s yearly income then is about thirty-one million days’ labor. Out of this you must pay for expenses, under your system, two million days’ labor for government taxes, fifteen million days’ labor for ground rent, two million days’ labor for water, two million days’ labor for insurance, and with the balance of ten million days’ labor you must pay the cost of food, raiment, fuel, the portion of rent estimated in buildings, together with the various incidentals of furniture and house lights. You will observe that all these expenses except the first are largely loaded with the profits of capital, so that with the income and expense as set forth you may be in a progressive condition, as that term is defined by you. That is to say, your capital may increase, and your wealth may be very greatly augmented. The enormous proportion of your earnings carried away by rent, although drawn very largely from your business districts, is contributed equally by the whole in the increased cost of all products consumed. Of your one hundred thousand producers, it is safe to say that twenty thousand of them have capital investments. Among these is divided the whole of the surplus of the city’s earnings. The eighty thousand engaged in the business of directly creating wealth are doomed, under your cruel system, to sweat and toil from sun to sun without accumulations. You accept this condition of things as inevitable, and your economists contend that the real or natural remuneration of labor is the bare means of subsistence. We have seen the unrighteous origin of this prodigious fund, which absorbs one third of the earnings of labor at least: let us examine its perpetual effects upon the interests of those who toil.
