This is a confirmation of what Marx explained in Capital, discussing the nature of agricultural production under capitalism: “All progress in capitalistic agriculture is a progress in the art, not only of robbing the labourer, but of robbing the soil; all progress in increasing the fertility of the soil for a given time, is a progress towards ruining the lasting sources of that fertility… Capitalist production, therefore, develops technology… only by sapping the original sources of all wealth — the soil and the labourer.”
