Murder, maiming and vitriol throwing are offences punishable by law. So are, or ought to be, rattening and intimidation. But there are ways less openly criminal of interfering with the liberty of non-union men. The liberty of non-union men, however, must be protected. Freedom of contract is the only security which the community has against systematic extortion; and extortion, practised on the community by a Trade Union, is just as bad as extortion practised by a feudal baron in his robber hold. If the unions are not voluntary they are tyrannies, and all tyrannies in the end will be overthrown. The same doom awaits all monopolies and attempts to interfere with the free exercise of any lawful trade or calling, for the advantage of a ring of any kind, whether it be a great East India Company, shutting the gates of Eastern commerce on mankind, or a little Bricklayers' Union, limiting the number of bricks to be carried in a hod. All attempts to restrain or cripple production in the interest of a privileged set of producers; all trade rules preventing work from being done in the best, cheapest and most expeditious way; all interference with a man's free use of his strength and skill on pretence that he is beating his mates, or on any other pretence, all exclusions of people from lawful callings for which they are qualified; all apprenticeships not honestly intended for the instruction of the apprentice, are unjust and contrary to the manifest interests of the community, including the misguided monopolists themselves. All alike will, in the end, be resisted and put down. In feudal times the lord of the manor used to compel all the people to use his ferry, sell on his fair ground, and grind their corn at his mill. By long and costly effort humanity has broken the yoke of old Privilege, and it is not likely to bow its neck to the yoke of the new.
