29. Every tax is a burden, and in the nature of the case can be nothing else. In mathematical language, every tax is a quantity affected by a minus sign. If it gets peace and security, that is, if it represses crime and injustice and prevents discord, which would be economically destructive, then it is a smaller minus quantity than the one which would otherwise be there, and that is the gain by good government. Hence, like every other outlay which we make, taxes must be controlled by the law of economy--to get the best and most possible for the least expenditure. Instead of regarding public expenditure carelessly, we should watch it jealously. Instead of looking at taxation as conceivably a good, and certainly not an ill, we should regard every tax as on the defensive, and every cent of tax as needing justification. If the statesman exacts any more than is necessary to pay for good government economically administered, he is incompetent, and fails in his duty. I have been studying political economy almost exclusively for the last fifteen years, and when I look back over that period and ask myself what is the most marked effect which I can perceive on my own opinion, or on my standpoint, as to social questions, I find that it is this: I am convinced that nobody yet understands the multiplied and complicated effects which are produced by taxation. I am under the most profound impression of the mischief which is done by taxation, reaching, as it does, to every dinner-table and to every fireside. _The effects of taxation vary with every change in the industrial system and the industrial status_, and they are so complicated that it is impossible to follow, analyze, and systematize them; but out of the study of the subject there arises this firm conviction: taxation is crippling, shortening, reducing all the time, over and over again.
