But it patently is all a completely idle question, in point of material advantage, to anyone but the owners of the vessels; and to these owners it is also of no material consequence under what flag their investments sail, except so far as the government in question may afford them some preferential opportunity for gain,--always at the cost of their fellow citizens.

The like is equally true as regards the domicile and the national allegiance of the businessmen who buy and sell the country's imports and exports.

The common man plainly has no slightest material interest in the nationality or the place of residence of those who conduct this traffic; though all the facts go to say that in some puzzle-headed way the common man commonly persuades himself that it does make some occult sort of difference to him; so that he is commonly willing to pay something substantial toward subsidising businessmen of his own nationality, in the way of a protective tariff and the like.
The only material advantage to be derived from such a preferential trade policy arises in the case of international hostilities, in which case the home-owned vessels and merchants may on occasion count toward military readiness; although even in that connection their value is contingent and doubtful.

But in this way they may contribute in their degree to a readiness to break off peaceable relations with other countries.

It is only for warlike purposes, that is to say for the dynastic ambitions of warlike statesmen, that these preferential contrivances in economic policy have any substantial value; and even in that connection their expediency is always doubtful.
