The crucial point is this. The basic income is not paying people for their otherwise unpaid work: it is providing them with the financial investment that makes it possible for them to do it. Investment in people is not "something for nothing", but sound economic practice. It is also what people deserve.
If any of these factors have more of an effect than the OBR has suggested then the Chancellor will find he has far more room for manoeuvre.
