The Biden admin certainly contributed to inflation in a massive degree. It's always a nigh-constant thing under the system, sure, but alongside the Ukraine war (which as someone else mentioned effected grain prices- but more than that has led to the crumbling of the western levers of finance, etc) and his continuation and even intensification of the Trumpian trade wars and antagonizing China, he's been running off that money printer in what I feel may as well be considered some of the largest wealth transfers to big tech/the MIC... (I'd call it tossing "bad money* after bad" maybe lololol- toilet paper money down the drain to endless corruption because the neoliberal disease is honestly hilarious in how ineffective it is)

Mind you, Trump was also abysmal. And the contradictions of the system are really closing in on them all so whoever's next will probably be worse, and so on.
