The fixing of ordinary prices, not tolls, was thoroughly tried in the Middle Ages and failed. Nor has it been attempted since as to wages, except in New Zealand by arbitration, and in England and (as to public labor) in the State of New York and a few other States where we have a recent statute that all employment in public work (that is, work for any city, county, or town, or the State, or for any contractor therefor) must be paid for "at the usual rate of wages prevailing in the trade"; this principle, taken from the last form of the English Statute of Laborers, being passed in the interest of the laborers themselves and not of the employers, as it was in early England. The result of this first piece of legislation was to impose some twenty thousand lawsuits upon the city of New York alone; the laborers working for a year or two at the rates paid by the city and then, after discharge, bringing suit and claiming that they had not been paid the "usual rate" of the trade; and as there were very heavy penalties, it is said to have cost the city of New York many millions of dollars. In the same way the union idea of having all trades under the control of an organization was carried to its extreme result in the Middle Ages also, so that the guilds became all-powerful; they imposed their rules and regulations to such an extent that it was almost impossible for any man to get employment except by their permission and under their regulation, or without membership. They naturally developed into wealthy combinations, more of employers than of journeymen, until they ended as the richly endowed dinner-giving corporations that we see in the city of London to-day. In France, at least, they were considered the greatest menace to labor, and were all swept away at the time of the French Revolution amid the joy of the masses and the pealing of bells. Unfortunately, our labor leaders are sometimes scornful of history and unmindful of past example; the fact that a thing has been tried and failed or has, in past history, developed in a certain manner, carries no conviction to their minds. (1444) A servant in husbandry had to give six months' notice before leaving and wages were again fixed; and in 1452, the time of Jack Cade's Rebellion, one finds the first prototype of "government by injunction," that is to say, of the interference by the lord chancellor or courts of equity with labor and the labor contract, particularly in times of riot or disorder.
