I'm so confused anytime someone blames "greed" for price increases.
First of all, corporations aren't people. And therefore, they cannot since, and cannot be greedy. They are inhuman profit maximizing machines. They always have been. Blaming "greed" doesn't make sense because (a) it anthropomorphizes corporations, (b) "greed" has been constant across this time frame.
If greed were to blame for these price increases, then why were prices not rising like this for every other year in living memory? Blaming greed for price increases is like saying a building burned down in a fire because of all the oxygen in the atmosphere. Like... sure? I guess that's true? But what is the takeaway? Being opposed to oxygen?
Back on topic - if you say the problem is greed, what policy proposals do you have to solve this problem? Greed is literally a biblical sin - what is your proposal to ban what is essentially one of the key components of human nature?
