"government spending causes inflation is a pretty mainstream ideological precept - the opposite opinion is fringe."
Hoo boy.
"the current Fed chair, Jerome H. Powell, has dismissed claims that the Fed’s money-printing is fueling today’s price spiral, emphasizing instead the disruptions associated with reopening the economy. Like his most recent predecessors, dating to Alan Greenspan, Powell says that financial innovations mean there no longer is a link between the amount of money circulating in the economy and rising prices"

You're right that the idea government money printing doesn't cause inflation is fringe absurdity. Unfortunately the fringe that believes in it are central bankers.
