National surveillance and regulation of business traffic in these countries hitherto, ever since and in so far as the modern democratic order of things has taken effect, has uniformly been of the nature of interference with trade and investment in behalf of the nation's mercantile community at large, as seen in port and shipping regulations and in the consular service, or in behalf of particular favored groups or classes of business concerns, as in protective tariffs and subsidies. In all this national management of pecuniary affairs, under modern democratic principles, the common man comes into the case only as raw material of business traffic,--as consumer or as laborer. He is one of the industrial agencies by use of which the businessman who employs him supplies himself with goods for the market, or he is one of the units of consumptive demand that make up this market in which the business man sells his goods, and so "realises" on his investment. He is, of course, free, under modern principles of the democratic order, to deal or not to deal with this business community, whether as laborer or as consumer, or as small-scale producer engaged in purveying materials or services on terms defined by the community of business interests engaged on so large a scale as to count in their determination. That is to say, he is free _de jure_ to take or leave the terms offered. _De facto_ he is only free to take them--with inconsequential exceptions--the alternative being obsolescence by disuse, not to choose a harsher name for a distasteful eventuality. The general ground on which the business system, as it works under the over-ruling exigencies of the so-called "big business," so defines the terms of life for the common man, who works and buys, is the ground afforded by the principle of "charging what the traffic will bear;" that is to say, fixing the terms of hiring, buying and selling at such a figure as will yield the largest net return to the business concerns in whom, collectively or in severalty, the discretion vests. Discretion in these premises does not vest in any business concern that does not articulate with the system of "big business," or that does not dispose of resources sufficient to make it a formidable member of the system. Whether these concerns act in severalty or by collusion and conspiracy, in so defining the pecuniary terms of life for the community at large, is substantially an idle question, so far as bears on the material interest of the common man. The base-line is still what the traffic will bear, and it is still adhered to, so nearly as the human infirmity of the discretionary captains of industry will admit, whether the due approximation to this base-line is reached by a process of competitive bidding or by collusive advisement.
