I am skeptical whether "greedflation" is a real phenomenon. Corporations were no less greedy a few years ago. Recent high inflation rates are more likely connected to monetary policy.
Not sure if you have insight to supply chain costs and how they inflated cost during the pandemic, but me and most I know who do understand the truth behind the greedflation dynamic
No; prices went up fast but there is nothing to drive them back down (ie competiton) even with inputs costs having declined due to monetary policy. Ergo, inflation was used as cover to hold prices high long after their cause had subsided.
Even with no competition you can’t keep putting prices up unless your customers have the means to pay. Competition didn’t suddenly change, it was the means to pay that did.
