1. That it bear as lightly as possible upon production—so as least to check the increase of the general fund from which taxes must be paid and the community maintained.
2. That it be easily and cheaply collected, and fall as directly as may be upon the ultimate payers—so as to take from the people as little as possible in addition to what it yields the government.
3. That it be certain—so as to give the least opportunity for tyranny or corruption on the part of officials, and the least temptation to law-breaking and evasion on the part of the taxpayers.
4. That it bear equally—so as to give no citizen an advantage or put any at a disadvantage, as compared with others.
Let us consider what form of taxation best accords with these conditions. Whatever it be, that evidently will be the best mode in which the public revenues can be raised.
I.—The Effect of Taxes upon Production.
All taxes must evidently come from the produce of land and labor, since there is no other source of wealth than the union of human exertion with the material and forces of nature. But the manner in which equal amounts of taxation may be imposed may very differently affect the production of wealth. Taxation which lessens the reward of the producer necessarily lessens the incentive to production; taxation which is conditioned upon the act of production, or the use of any of the three factors of production, necessarily discourages production. Thus taxation which diminishes the earnings of the laborer or the returns of the capitalist tends to render the one less industrious and intelligent, the other less disposed to save and invest. Taxation which falls upon the processes of production interposes an artificial obstacle to the creation of wealth. Taxation which falls upon labor as it is exerted, wealth as it is used as capital, and as it is cultivated, will manifestly tend to discourage production much more powerfully than taxation to the same amount levied upon laborers, whether they work or play, upon wealth whether used productively or unproductively, or upon land whether cultivated or left waste.
The mode of taxation is, in fact, quite as important as the amount. As a small burden badly placed may distress a horse that could carry with ease a much larger one properly adjusted, so a people may be impoverished and their power of producing wealth destroyed by taxation, which, if levied in another way, could be borne with ease. A tax on date-trees, imposed by Mohammed Ali, caused the Egyptian fellahs to cut down their trees; but a tax of twice the amount imposed on the land produced no such result. The tax of ten per cent. on all sales, imposed by the Duke of Alva in the Netherlands, would, had it been maintained, have all but stopped exchange while yielding but little revenue.
But we need not go abroad for illustrations. The production of wealth in the United States is largely lessened by taxation which bears upon its processes. Ship-building, in which we excelled, has been all but destroyed, so far as the foreign trade is concerned, and many branches of production and exchange seriously crippled, by taxes which divert industry from more to less productive forms.
This checking of production is in greater or less degree characteristic of most of the taxes by which the revenues of modern governments are raised. All taxes upon manufactures, all taxes upon commerce, all taxes upon capital, all taxes upon improvements, are of this kind. Their tendency is the same as that of Mohammed Ali’s tax on date-trees, though their effect may not be so clearly seen.
