The success of the Dockers is no measure of the power of combination among low-skilled labourers.

It is possible, however, that a growing sense of comradeship, aided by a general recognition of the justice of a claim, may be generally relied upon to furnish a certain force which shall restrict the competition of free labour in critical junctures of the labour movement.

If public opinion, especially among workmen, becomes strongly set in favour of letting capital and labour "fight it out" in cases of trade disputes, and vigorously resents all interference of outsiders offering to replace the contending labourers, it seems likely that this practical elimination of outside competition may enable combinations of unskilled workmen to materially improve their condition in spite of the existence of a large supply of outside labour able to replace them.
Sec.6.Can Trade Unionism crush out "Sweating" ?--But here again it must be recognized that each movement of public opinion in this direction is really making for the establishment of new trade monopolies, which tend to aggravate the condition of free unemployed labour.

Unions of low- skilled labour can only be successful at the expanse of outsiders, who will find it increasingly difficult to get employment.

The success of combinations of low-skilled workers will close one by one every avenue of regular employment to the unemployed, who will tend to become even more nomadic and predatory in their habits, and more irregular and miserable in their lives, affording continually a larger field of operation for the small "sweater," and other forms of "arrested development" in commerce.
