Not only as a matter of justice and honesty, but as a matter of prime popular interest, we should see that this control is so exercised as to favor a proper return to the upright business manager and honest investor. In the matter of railway rates, for instance, it is just as much our duty to see that they are not too low as that they are not too high. We must preserve the right of the railway employee to proper wages and the right of the investor to proper interest as scrupulously as we preserve the right of the shipper and the producer and the consumer. We cannot afford to do injustice, or suffer it to be done, to any of these. But in order to do justice we must have full knowledge. We must have the right to find out every fact connected with the business of the railway, so as to base our judgment, not on any one fact, but on all taken together. Inasmuch as it is so often impossible to punish wrongs done in the past, and to prevent the consequences of the wrongs thus committed being felt by one innocent class, without shifting the burden to the shoulders of another innocent class, we ought to provide that hereafter business shall be carried on from its inception in such a way as to prevent swindling. Incidentally, this will also tend to prevent that excessive profit by one man, which may not be swindling, under existing laws, but which nevertheless is against the interest of the commonwealth; To know all the facts is of as much interest to the investor and the wageworker as to the shipper, the producer, the consumer. Full knowledge of the past helps us in dealing with the future. If we find that high rates are due to overcapitalization in the past, or to any kind of sharp practice in the past, then, whether or not it is possible to take action which will partly remedy the wrong, we are certainly in a better position to prevent a repetition of the wrong.
