A core factor behind inflation is the cost of delivering products to retailers. A core causes of higher fuel prices- Trump's agreement (blackmail, actually) with the Saudis to get OPEC+ to cut production because, in his words, "Low gas prices are bad for Americans". And with oil costs per barrel so high, OPEC+ doesn't want to increase production- they're not stupid, petroleum is slowly being phased out as fuels, so they want to get the money while the getting's good.

Baby formula- most came from Canada until Trump put a 17.7% tariff on it- having baby formula must be bad for Americans, too.

Add in the high tariffs on imports from China and many other nations and prices were forced up.

There is no supply chain problem in the oil industry. If there were, gas stations would be running of gas- has anyone not been able to buy gas? No. And big oil likes the record profits they're earning but aren't sharing any of them with their consumers.

Biden is in the WH so of course he's blamed for every ill we have, here and worldwide.
