Pérdida del poder adquisitivo versus disminución del tiempo de trabajo socialmente necesario

Workers in any latitude on the planet lose purchasing power with respect of the resources they obtain for the payment of their wages. There is a tendency that is contrary to the decrease in purchasing power, it is the decrease in socially necessary work time. This law consists of measuring the time required to perform tasks both inside the work and in daily life. Technological development encompasses all activities and makes it possible to reduce the required effort in each social space. Both economic trends are part of a general law called downward trend in the rate of profit. In this work theoretical reflections originated in classic authors are exposed.
