Book excerpt: The present publication constitutively expands the field of discourse on the topic of basic income and explores the possibilities of its introduction as well as the opportunities and risks. Although all visionary proposals for an unconditional basic income UBI/BGE, have so far not been implemented politically, at least in democratically constituted welfare states, the question of implementation or the conditions for success and the identification of possible blockades have only been dealt with marginally. Recent publications on a BGE also show this political-institutional "blindness" and do not address enough the reasons for the failure so far. Without a transfer strategy, however, the idea will fail in Germany due to such implementation naivety. In this book, therefore, the state of the debate on basic income is developed further to the extent that it is integrated into welfare-state development processes and current challenges for the "safeguarding of social security". In addition, a social-scientific classification of hitherto visionary guarantee elements of a basic income model is undertaken, linking up with the "silent" change to a socially investing state.

A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation.
