Prove me wrong.
You are saying that no price reductions can occur unless an equivalent and corresponding price reduction is made at every production step.
According to that "logic", if an airline company was able to reduce its labor costs by $5 million, they would be unable to lower prices by an equivalent amount.
According to that "logic", a grocery store that found a cheaper farmer from whom to buy its groceries would not be able to reduce prices at all?
What are you talkin' about?
