When demand is higher than supply and when there is no competition greedflation will exist. If demand is low raising prices won't help the seller; it will just reduce demand further. If there is competition then sellers will try to differentiate their product from the other sellers. One way of doing that is lowering the price. Does anyone dispute that?

Btw, the core inflation rate dropped to 4.9% in May, down from 9.1% last June, and the FED is projecting it to drop to 3.5% by the end of the year, obviously assuming there are no shocks (new wars, droughts, asteroids hitting the planet) to the market.

Certainly greed exists. Certainly the desire to profit through exploitation exists. But it is no match for market competition. Companies can greedflation themselves right out of business if competitors offer the same product or service for a better price. This is intuitive. If there is a gas station on every corner of an intersection, and three of them are charging about $3.50/gallon, but one of them has a greedy owner who is charging $5.50/gallon, do you really think he will make more money than the others?
