While one accepted economic law thus declares that all value is conferred by the labourer, and is simply his sweat, brain, and sinew incorporated in the product, another economic law declares that he gains no advantage from the productivity of his own work, and that whatever value he produces, he earns only the same wages--bare customary subsistence. In that lies the alleged injustice of the present system. Von Thuenen, the famous Feudalist landowner and economic experimentalist, said, many years ago, that when the modern working class once began to ask the question, What is natural wages? a revolution might arise which would reduce Europe to barbarism. This is the question Lassalle asked, and by which mainly he stirred up socialism. The effect of the previous argument was to raise the question, What is the labourer entitled to get? and to suggest the answer, he is entitled to get everything. The next question is, What, then, does the labourer actually get? and the answer is, that on the economists' own showing, he gets just enough to keep soul and body together, and on the present system can never get any more. Ricardo, in common with other economists, had taught that the value of labour, like the value of everything else, was determined by the cost of its production, and that the cost of the production of labour meant the cost of the labourer's subsistence according to the standard of living customary among his class at the time. Wages might rise for a season above this level, or fall for a season below it, but they always tended to return to it again, and would not permanently settle anywhere else. When they rose higher, the labouring class were encouraged by their increased prosperity to marry, and eventually their numbers were thus multiplied to such a degree that by the force of ordinary competition the rate of wages was brought down again; when they fell lower, marriages diminished and mortality increased among the working class, and the result was such a reduction of their numbers as to raise the rate of wages again to its old level. This is the economic law of natural or necessary wages--"the iron and cruel law" which Lassalle declared absolutely precluded the wage-labourers--_i.e._, 96 per cent. of the population--from all possibility of ever improving their condition or benefiting in the least from the growing productivity of their own work. This law converted industrial freedom into an aggravated slavery. The labourer was unmanned, taken out of a relationship which, with all its faults, was still a human and personal one, put under an impersonal and remorseless economic law, sent like a commodity to be bought in the cheapest market, and there dispossessed by main force of competition of the value of the property which his own hands had made. _Das Eigenthum ist Fremdthum geworden._
