Thus the people accumulate wealth until its retirements and the trend is that this accumulation diminishes when this date in fact arrives. At the beginning of this cycle the people are entering for the work market and its initial income normally is minor who in the long stated period, and in believing that they will go to have an increase in the income level these people will be able to use the credit available what it inhibits in this stage the increase of the saving level. Already at as a moment, in the second part of the cycle, the increase of the waited income will concur so that the before done loans are paid and from I accumulate it to the payment of capital for the retirement in fact occurs. In one another hypothesis the young passes for a case of restriction for liquidity in which they do not obtain loans, of this form its available income will be all directed toward the consumption, in the second phase the people had thus only obtained to start to accumulate wealth given the credit lack to these.
