The strongest argument is probably that for someone subsisting on the minimal wage, the CPI is not a good representation of their consumption basket (whereas it might be for someone close to the median).
Therefore the adjustment should probably be based on a different number reflecting the actual consumption of households near the poverty line (food would probably be higher than it is in the CPI currently, as one example)
