Marx called this valorization.

"Just as capital, as value valorizing itself, views with indifference the particular physical guise in which labour appears in the labour process, whether as a steam-engine, dung heap or silk, so too the worker looks upon the particular content of his labour with equal indifference. His work belongs to capital, it is only the use-value of the commodity that he has sold, and he has only sold it to acquire money and, with the money, the means of subsistence."
