In proportional or equal taxation, whereby every property owner contributes toward the expenses of the common government according to the amount of property he owns or inherits, or according to the income he enjoys, we find a perfectly safe and consistent rule and a definite and logical principle upon which to work. Proportional taxation subjects to the burden of government fairly and equally all property owners without distinction and without discrimination. Nothing is left to mere discretion or to the play of arbitrary and irresponsible power, and no class is likely to be unjustly singled out or discriminated against. Where property is as generally distributed as it is in this country, a proportional tax ordinarily reaches in one form or another a majority of the constituents of those who vote the taxes, and the sense of responsibility to these constituents operates as a conservative force and as a check upon unfair and unjust taxes, as well as upon improvident and extravagant expenditures. A proportional tax generally creates a large body of tax-paying voters whose property interests impel them to watch their representatives closely and to hold them to strict accountability. We then have taxation in its practical operation going hand in hand with representative responsibility, which was the cardinal principle for which our War of Independence was fought. A legislator who is conscious of the fact that a large, if not a controlling, number of his constituents will feel the burden of any tax he votes, is necessarily more careful, more prudent, more economical and more inclined to be just than if no such sense of responsibility exists. On the other hand, where the great majority of voters are to be exempted from taxation, and where, accordingly, they will feel that they have no personal interest in governmental expenditures, they will be likely to take little or no pains to see that there is a fair apportionment of taxes which others must pay, or any economy in governmental expenditures for which others must provide. Their sense of justice and civic duty will become blunted. It will follow that, if the lawmakers are at liberty to enact laws which exempt the great majority of their constituents from taxation and cast the burden and expense of government on the few rich, frequently less than two or three per cent. of the voters in their respective districts, there will exist no practical restraint upon expenditure, but, on the contrary, every temptation to extravagance, wastefulness and injustice.
