Consider a situation where certain taxes have been for some time levied. They have become a part of the general adjustment of prices. If paid by any one in business they may be looked upon as a deduction from the gross proceeds or product of the business, prior to cost, or as a part of cost.[7] In either case every one choosing that business does so in the light of this fact. Unless the business promises to yield as good incomes (wages, profits) as other lines, the number engaging in it, and the output, must diminish and thus the price of the product rise, or the cost of the factors fall, or both in some proportion. The tax on any durative agent or on any established business thus becomes incorporated after a time in its price and in the prices of the products, and any purchaser pays a price based on the net income remaining to the owner of the wealth after the tax is paid. Viewed in this way, taxes are seen to be borne to some extent by every one, by those who do not as well as by those who do actually meet the tax-collector face to face. The citizen with no taxable property is affected, far more than he realizes, by extravagance of government and by inequities in taxation, for the effects of most taxes are diffused so that every self-sustaining member of the community has some share in them. § 15. #Taxes as costs.# Now if a new tax is levied, or an old tax changed in amount or in its incidence, it becomes a new influence in industry. Some occupations are made more attractive, others less so. Some places are made more, others less, desirable to live in. Property thus fluctuates in value, and investments become more or less remunerative. If the new tax reduces the net income of any productive agent, it reduces likewise its value, which is but the capitalization of its net rental. If taxes are taken off of factories and put upon farm rents, factories rise and farms fall in value in the hands of their owners. The immediate change in value is much greater than the annual tax, for if five dollars is to be taken permanently from the annual rental of the farm, nearly one hundred dollars is taken at once from its selling value when the prevailing yield on investment is 5 per cent. The rate of adjustment varies greatly under different conditions, and the inflow and the outflow of labor and capital are more or less rapid in the various industries.
