Karl Marx emphasized that with few exceptions means of labour are not a productive force unless they are actually operated, maintained and conserved by living human labour. Without applying living human labour, their physical condition and value would deteriorate, depreciate, or be destroyed (an example would be a
ghost town or capital depreciation due to
strike action). Simultaneously, technological developments which serve as means of production would not exist without what Marx refers to as "general intellect," the human innovation and industry which motivates industrial development. Capital itself, being one of the
factors of production, comes to be viewed in capitalist society as a productive force in its own right, independent from labour, a subject with "a life of its own". Indeed, Marx sees the essence of what he calls "the capital relation" as being summarised by the circumstance that "capital buys labour", i.e. the power of property ownership to command human energy and labour-time, and thus of inanimate "things" to exert an autonomous power over people. What disappears from view is that the power of capital depends in the last instance on human cooperation. The productive power of cooperation comes to be viewed as the productive power of capital, because it is capital which forcibly organises people, rather than people organising capital. Marx regarded this as a supreme
reification. Unlike British classical economics,
Marxian economics classifies financial capital as being an element of the relations of production, rather than the factors or forces of production ("not a thing, but a social relation between persons, established by the instrumentality of things"). == Destructive forces ==
