Supply chain issues definitely do cause inflation. Don't you remember what happened to car prices when the manufacturers couldn't buy enough chips for them?

Now that they can buy enough, why is there no corresponding drop in car prices and deflation?

They are:

3 years of monthly increases, and a small one month drop. When they return to what they were 3 years ago, we can talk.

Not true -- inflation can be caused by multiple things, including supply shocks or even future expectations of inflation ("wage price spiral").

It's Econ 101.

Your Econ 101 professor is wrong.

The proof is simple. Why did we not have deflation when the supply shocks ended?

The value of money is subject to the Law of Supply and Demand like everything else is. Increase the number of dollars, and the value of a dollar goes down.

Probably due to low unemployment [1]. Inflation has multiple causes.

If it truly has a single cause ("creating money"), can you show a graph of "money created" vs inflation? I don't see much correlation between ∆M2 and inflation [2].

Looks like they correlate to me.
