The same way supporters of the greedflation hypothesis defend their position on corporate greed: by claiming it increased substantially in recent years. Except the money printing hypothesis champions have more convincing data.
> the money printing hypothesis champions have more convincing data
they really don't though, that's the point. they've been screaming that all the "money printing" is going to cause hyperinflation any day now for decades. eventually yeah we got some inflation, even a broken clock is right twice a day. their ideas have zero explanatory power. (if they did, how come we didn't get hYpErInFlaTioN decades ago, and STILL don't have it today?)
Money printing increased significantly in the past few years, as did inflation. Taking the most extreme version of the argument and using inconsistent capitalization when quoting it doesn’t stop inflation from being a monetary phenomenon.
