Such problems are peculiarly unfit for treatment by our central Government. Its chief duty, of course, is protection of our people against invasion and rebellion; and the authority of the President and Congress ought not to be weakened by vain attempts to settle disputes which would be dealt with much more satisfactorily by the cities and towns. A Sunday law too lax for Pennsylvania might be too strict for California. The system of post-offices is too well adapted for the general welfare to be given up hastily; but the Government ought to surrender the monopoly which now makes it almost impossible for citizens to free themselves from dependence on disobliging or incompetent postmasters. I have nothing to say against the Census, Education, Health, and Patent Bureaus, nor against the Smithsonian Museum, except that our citizens have a right to use their own property as freely on Sunday as on any other day of the week. I do not see why our Government should have more than that of other nations to do with the issue of paper money; but I leave the bank question to abler pens. The tariff is a much plainer issue. We are told in _Social Statics_ that "A government trenches upon men's liberties of action" in obstructing commercial intercourse; "and by so doing directly reverses its function. To secure for each man the fullest freedom to exercise his faculties, compatible with the like freedom of all others, we find to be the state's duty. Now trade-prohibitions and trade-restrictions not only do not secure this freedom, but they take it away, so that in enforcing them the state is transformed from a maintainer of rights into a violator of rights." The obstacles to importation deliberately set up by American tariffs, indirectly check exportation; for unwillingness to buy from any other nation diminishes not only its willingness but its ability to buy our products in return. The United States are actually exporting large amounts of cattle, wheat, and cotton, as well as of boots and shoes, agricultural implements, steel rails, hardware, watches, and cotton cloth. These commodities are produced by Americans who can defy foreign competition. In some cases the tariff enables them to raise their prices at home, to the loss of their fellow-citizens. Prices abroad cannot be raised by our Government. What it can and does do is to burden both farms and factories by duties on lumber, glass, coal, wool, woollen goods, and many other imports. The rates are arranged with a view to increase, not individual liberty or public security, but the profits of managers of enterprises which would not pay without such help. Men who are carrying on profitable industries have to make up part of what is lost in unprofitable ones. In fact, the cost of living is increased needlessly for all our citizens, except the privileged few.
