Another approach
We can lean on strengths already there although potential, to develop society and come out finally of the " phase of transition ". It requires an awareness of their importance from the edges of the society which could bring a new vision.
This new vision consists in applying to every domain the principle proposed by Einstein ("We can't solve problems by using the same kind of thinking we used when we created them. "). So, the problem of the pensions can't be solved with the extension of life. Undoubtedly other tracks would appear if things were thought differently and if the word pension was changed in ''free activity'': a person able to choose freely her activity can decide to be idle, but can also have a social activity in which her level of involvement will be much higher (see the difference between ''to mobilize'' and to ''get involved'': Internet Tome 2 - services and practices of tomorrow - chapter 7: the appropriation of the practices – frame on cooperative projects - page 97).
Thus, stopping to see only the constraints, we can focus on opportunities and develop new solutions.
