The rights to impartial and to equal treatment need not detain us long. There is no right to impartiality except where impartiality is due, and it is only in a small minority of cases that impartiality is due. There is nothing iniquitous in showing favour to the extent of giving one person more than his due, provided no other person be prevented from having as much as his due. The lord of the vineyard who gave unto all his labourers alike, the same to those who had wrought for him but one hour as to those with whom he had agreed that for a penny they should bear the burden and heat of the day, did the latter no wrong; his eye was not the less good because theirs was evil. A judge, or an arbitrator, or the conductor of a competitive examination, is bound to make his award without respect of persons, because he cannot favour one without withholding from some other what that other ought to have. On every distributor of Government patronage, likewise, it is morally incumbent to select for the public for whom he is trustee, the best servants he can find. An English Prime Minister has no right to make his son a Lord of the Treasury or of the Admiralty, if he know of any one better fitted for the post and willing to accept it; and if he name any but the fittest candidate, he fails in his duty to the community on whose behalf he acts. But a private employer, acting for himself alone, is under no similar obligation, and may take whom he pleases into his service, and assign to him whatever position therein he pleases, without affording any cause for reasonable complaint to those more capable members of his establishment whom he places under one less capable. In short, except in those rare cases in which impartiality means rendering what is due, in which cases it is but another name for justice, there is nothing unjust in disregarding it.
