Different country, but I've noticed that social assistance are linked to the CPI yet the CPI is linked to items that those who receive social assistance cannot afford and which are less impacted by inflation (at least under normal circumstances, I'm not sure about the current situation). I'm not sure about the intent though. When the government first announced COVID benefits it was quickly revealed that they had no understanding what most vulnerable members of society were facing. It took several rounds of announcements until everyone was satisfied. Likewise, the article's comment about pay increases for public sector employees made me cringe. At least on this side of the pond, the public sector has been hit hard and is in chaos since pay is based upon union contracts that were pre-pandemic. In some cases, union contracts expired early in the pandemic but where negotiations were stalled until recently due to the pandemic.
