(Marx, 1982:107) the reduction of the necessary time the manufacture of the product of the work did not mean a reduction of the hours of working, quite to the contrary, the capital beyond appreciating the destitution of the worker with the long day was capable of reduziz it condition of superfluous and thus to diminish gradual the necessity of the alive work. The capital is not only detainer of the material necessities to the work (substance cousin and means of production). The value used in the production of a merchandise (hand of workmanship, substance cousin and used time) alavancado by the development of the industrial technology, more does not define the social value of this merchandise, being this difference the conceptualization of more-value, appropriate for the capitalists. The dialectic between the capital and work is developed until the height of its contradiction (or beginning of this apex) in the way that the first one would be capable to force the other in the same speed where if it develops. This violence is in the intention to diminish the amount of employed workers (through the use of the machine) and to increase the hours of working. this seems obligator task for the increase of the production in the molds of the capital.
The Marx are not against the development of the technology, ' ' in first place, he must be clearly that the machinery is good because it saves trabalho' ' (MARX, 1982:109). The critical one is based in the use of this technology for ones, as instrument of domination on others. The development of the work served as structure for the distinction of the man with the remain of the organic world, however the dependence is mutual. The alteration of the nature is not summarized to the disappearance of the same one. Joe Leytze does not necessarily agree. The work and the modifications in the way to produce appear as development mechanisms that expand the proper on question to the work, the man when modifying the nature will be also modifying itself, therefore to leave, in such a way appear a new agreement of the proper nature, while half of natural resources, how much of the proper form in if improving the way to modify this nature.
