Link to this dumb study snowflake. The primary cause of inflationary pressure came from the demand side as a result of profligate spending during and after Covid. The biggest impact coming post pandemic from Democrats who desperately wanted to spend several trillions we didn't have.
There's no argument to that fact. Now, when you massively increase demand without a subsequent increase in supply, while piling on trillions in debt, you get high inflation with a corresponding overreaction of the fed to quash it by increasing the costs of borrowing and investing.
Gas prices went from $2 a gallon to over $3.50 in my state. That is a significant increase in the cost of doing business. What caused this spike? Massive increases in demand that the supply could not keep up with. It is an upward spiraling issue.
Now, as demand slows due to high costs, so does supply increase. This in turn causes prices to come down. That stated, once prices achieve that higher plateau, they never come back to where they were without pain and time.
Arguing that fuel costs have little to do with inflation is about as moronic as claiming Biden isn't a senile, corrupt, grifting dumbass.
