Renta básica y constitución en el Estado Social alemán. (De la renta básica universal a la renta básica colectiva)

At present, the precarious jobs do not assure the subsistence level, and the future forecasts «the end of work». In addition, because of the defects and limits of the welfare systems, a rethinking of the social protection system is necessary: universal basic income seems to be the most popular option. Although the basic income is usually based on the idea of social reform, the perception of this study is that its implementation should be guided by a policy of small advances, which ultimately make possible a partial reform of the Social Security system, not its dismantling. There are currently examples with these characteristics, for specific groups (e.g. minors in Germany) to which a basic income is being granted. Without a doubt, it is a big step in that direction, which can serve as a model to be followed by all legal systems ¿among them Spanish one¿ that follow a system of generational distribution (pay-as-you-go system) in pensions.
