I was just giving one scenario, though unlikely, in which consumer spending does not increase whatsoever. It is likely that a large fraction, maybe even a majority, of basic income would go to paying off debt rather than consumer spending. Given that there is such a huge amount of personal debt out there, the poor have the freedom to allocate their basic income between spending and paying off debt for many years. And when prices go up for certain things, they might reallocate their income to other things.
