Do yourself a HUGE favor and look at inflation around the world. Look at gas prices on the global markets. This isn't a US only problem - we don't have to be using a universal currency for global scarcity to affect us. Every nation has suffered from supply chain issues in the wake of Covid, and every nation has suffered from high gas prices as a result of Russia's invasion of Ukraine (because gas is sold on a global market).

Yeah, not that difficult to figure out, if you're not myopic and actually know something about economics.

Honestly it would take an utter buffoon to not see this - you'd have to be willfully blind or completely incapable of basic causality.
