Hi there Mark! I’m afraid you seem to have got yourself rather confused. I am merely saying that, under a Basic Income system, people won’t, on average, need any more food per month or any more housing than they need now. That’s why we can be confident that Basic Income is fundamentally affordable — in terms of real resources.
As for the bureaucracy, Basic Income will be a set amount paid to every working age adult citizen per week. Children may get a lower amount. Pensioners may get more. It might be decided that Basic Income should be higher in some areas than in others. However, there is still no need for individual means-testing — so bureaucracy requirements will be drastically less than with most existing welfare systems.
I hope that explanation helps.
