Did Biden (when VP or in his previous career - he's been in politics for a very long time, after all) have any part in linking SS payments to inflation? That's the only way I could imagine such a claim for credit would have validity (though in that case it _would_ be a legitimate claim). Otherwise it's not actually an 'increase' in any case, it's just staying the same in real terms.
Here the "triple lock" (pensions rising in line with whichever is the larger of price-inflation, pay-inflation or 2.5%) is a very big deal for the Conservatives, who depend on the pensioner vote and so need to keep them happy.
But even that might be for the chop in their latest round of austerity. They really have thoroughly messed-up the economy - after 12 years in power, including a decade of austerity, mismanaging COVID, and then Truss's catastrophic budget, sorry "fiscal event" (more like "fisting event") and everything is now crap. Yet they constantly talk as if all the problems we are facing are some mysterious act-of-nature and nothing to do with them, even though THEY'VE BEEN IN POWER FOR 12 YEARS. That's after they previously blamed Gordon Brown for the effects of the GLOBAL financial crash.
I don't understand how they get away with this deception. Being right-wing means never having to take responsibility for anything you do, apparently.
