The viability of a specific institutional design, of course, may not be an all-or-nothing affair. It may crucially depend upon various kinds of side conditions. For example, a generous unconditional basic income may be viable in a country in which there is a strong, culturally rooted work ethic and sense of collective obligation, but not in a highly atomistic consumerist society. Or, a basic income could be viable in a society that had already developed over a long period of time a generous redistributive welfare state based on a patchwork of targeted programmes, but not in a society with a miserly, limited welfare state. Discussions of viability, therefore, tend also to include the contextual conditions of possibility for particular designs to work well.
