“The labour-power is a commodity, not capital, in the hands of the labourer, and it constitutes for him a revenue so long as he can continuously repeat its sale; it functions as capital after its sale, in the hands of the capitalist, during the process of production itself.”

“As the variable capital always stays in the hands of the capitalist in some form or other, it cannot be claimed in any way that it converts itself into revenue for anyone.”

Karl Marx (1818–1883) German philosopher, economist, sociologist, journalist and revolutionary socialist

“An increase in the productivity of labour means nothing more than that the same capital creates the same value with less labour, or that less labour creates the same product with more capital.”

Karl Marx (1818–1883) German philosopher, economist, sociologist, journalist and revolutionary socialist

“The division of labour is a consequence of the previous accumulation of capital… As the accumulation of capital must have preceded the division of labour, so its subsequent division can only be extended as capital is more and more accumulated. Accumulation and division act and react on each other. The quantity of raw materials which the same number of people can work up increases in a great proportion, as labour comes to be more and more subdivided; and acccording as the operations of each workman are reduced to a greater degree of identity and simplicity, he has, as already explained, a greater chance of discovering machines and processes for facilitating and abridging his labour. The quantity of industry, therefore, not only increases in every country with the increase of the stock or capital which sets it in motion; but, in consequence of this increase, the division of labour becomes extended, new and more powerful implements and machines are invented, and the same quantity of labour is thus made to produce an infinitely greater quantity of commodities”

John Ramsay McCulloch (1789–1864) Scottish economist, author and editor

“As a beast of toil an ox is fixed capital. If he is eaten, he no longer functions as an instrument of labour, nor as fixed capital either.”

Karl Marx (1818–1883) German philosopher, economist, sociologist, journalist and revolutionary socialist

“The capitalist is very fond of declaring that labour is a commodity, and the wage contract a bargain of purchase and sale like any other. But he instinctively expects his wage-earners to render him, not only obedience, but also personal deference. If the wage contract is a bargain of purchase and sale like any other, why is the workman expected to toff his hat to his employer, and to say ‘sir’ to him without reciprocity?”

Sidney Webb, 1st Baron Passfield book Industrial Democracy

“A class of labourers, who live only so long as they find work, and who find work only so long as their labour increase capital. These labourers, who must sell themselves piecemeal, are a commodity, like every other article of commerce, and are consequently exposed to all the vicissitudes of competition, to all the fluctuations of the market.”

Karl Marx (1818–1883) German philosopher, economist, sociologist, journalist and revolutionary socialist

“The annual produce of the land and labour of any nation can be increased in its value by no other means, but by increasing either the number of its productive labourers, or the productive powers of those labourers who had before been employed.”

Adam Smith (1723–1790) Scottish moral philosopher and political economist

“Capitalism is commodity production at the highest stage of development, when labor power itself becomes a commodity. The growth of internal exchange, and particularly of international exchange, is a special feature of capitalism. The uneven and spasmodic character of the development of individual enterprises, of individual branches of industry and individual countries, is inevitable under the capitalist system.”

Vladimir Lenin (1870–1924) Russian politician, led the October Revolution

“The news had stirred him strangely. He listened for bulletins on the radio, which he had seldom turned on after finding that its basic function was advertising things for sale.”
