No dole, no means tests, no concept of unemployment. The market economy goes on. Those who want to work and are genetically lucky enough to be able to learn skills that the market rewards do so and have more than the basic income to spend. Those who do not work include the genetically unlucky, who would find it hard to get a job, as well as those who are capable of almost anything but prefer to write poetry or play chess. Nobody bothers much which person is which.
Citizenship involves duties of community service as well as a right to the basic income.
There is a wide range of voluntary choice in the form of community service, but you make an annual service return as well as an income tax return, and the safeguards against cheating are similar in both cases. I find such a society attractive for several reasons. I belong to the same generation as Mrs. Thatcher, so when she and her ministers were railing at the welfare dependent, and saying how they ought to feel ashamed of themselves, I knew exactly what she meant. A basic income would obscure the distinction between those who would find it difficult to get a job and those who simply prefer to live modestly in order to play at being shepherds in the morning and literary critics in the afternoon. That should help with the dignity problem, which in my view is at least as serious an aspect of unemployment as the poverty problem.
