This seems very different from basic income discussed today. What they essentially describe is an expanded need-based assistance program. US provides a tax credit for very low income that essentially results in negative tax.
The Swiss referendum called for unconditional payment. To me, the unconditional nature is the preserving factor that incentivizes people to earn more, while knowing they are protected. A needs based system results in fear of losing what little you have. Low income housing in extremely desirable areas works in similar manner and traps people, instead of incentivizing them to seek higher paid employment because that higher pay will make them not qualified for the subsidy, yet not able to afford the area.
