Labour power
（重定向自Labor power）
Labour (in German: Arbeitskraft; in French: force de travail) is a crucial concept used by Karl Marx in his critique of capitalist political economy. Marx distinguished between the capacity to do work, labour power, from the physical act of working, labour. Labour power exists in any kind of society, but on what terms it is traded or combined with means of production to produce goods and services has historically varied greatly.
