Yes, understanding what's causing inflation matters. I'm not saying it doesn't. But when you have a crisis, you want to focus on mitigation first and then root causing it after the situation is averted.
Also you mention two possible causes of inflation. Limited resources and distribution, and companies deciding to raise prices because they can. What about the Fed printing money like crazy, flooding the M2 money supply? That's the one that's relevant to this conversation.
M2 is only relevant to a point. The increase in the money supply does not, in and of itself, cause any change in prices at all. Individuals and corporations have to make explicit decisions to respond to what they can see of the M2 effect, and none of these decisions are a law of nature. Rents don't have to go up just because M2 grew. Landlords sense that they can, and then they choose to do so. They could choose not to do so, too, but they don't because we're taught that this would be irrational, or something.
The law is called supply and demand. If there are more dollars and the same amount of resources, the value of a dollar goes down.
Let's just agree to disagree. Cheers.
Is a certain amount of rate increase justified? Yes, you don’t want an inflation spiral to develop. Beyond that, we are going to have to live with a certain amount of inflation until the situation in Eastern Europe normalizes and the supply chains normalize after COVID. And the interest rates should be kept on the lower side so that companies can still finance solutions to this mess.
The latter is only possible if there is too much money in the system, the signal about wheat production gets lost. As the feds money printer doesn’t work evenly, those who are closer to it get more money. I can only speculate that eventually, like any corruption, the effect is to diminish productivity in the real economy in favor of a special class.
When your employee is making gigantic profits, asking for more in wages has no relationship to the money supply.
They won't "normalize" though (imho), as the reason is not really COVID anymore, it is China gaining ground and trying to do as much damage to the western economy as possible.
