The first is the question of an Alien law limiting or prohibiting the migration of foreign labourers into England. The power of the German, Polish, or Russian Jew, accustomed to a lower standard of life, to undersell the English worker in the English labour market, has already been admitted as a cause of "sweating" in several city industries. The importance of this factor in the problem of poverty is, however, a much disputed point. To some extent these foreign labourers are said to make new industries, and not to enter into direct and disastrous competition with native workers. In most cases, however, direct competition between foreign and native workers does exist, and, as we see, the comparatively small number of the foreign immigrants compared with the aggregate of native workers, is no true criterion of the harm their competition does to low-waged workers. Whether this country will find it wise to reverse its national policy of free admission to outside labour, it is not easy to predict. The point should not be misunderstood. Free admission of cheap foreign labour must be admitted _primâ facie_ to be conducive to the greatest production of wealth in this country. Those who seek to restrict or prohibit this admission, do so on the ground that the damage inflicted upon that class of workers, brought directly or indirectly into competition for employment with these foreigners, overbalances the net gain in the aggregate of national wealth. It is this consideration which has chiefly operated in inducing the United States, Canada, and Australia to prohibit the admission of Chinese or Coolie labour, and to place close restrictions upon cheap European labour. Sir Charles Dilke, in a general summary of colonial policy on this matter, writes, "Colonial labour seeks protection by legislative means, not only against the cheap labour of the dark-skinned or of the yellow man, but also against white paupers, and against the artificial supply of labour by State-aided white immigration. Most of the countries of the world, indeed, have laws against the admission of destitute aliens, and the United Kingdom is in practice almost the only exception."[32]
