Look let me set things straight regarding what I believe.
First I agree with you that "price controls" don't work. You do not have to prove that point with me.
Having said that, I believe that all extremes are bad and that we need to walk the "middle road" and control greed to some degree. There is "some" price gouging going on (we all know it) but on the other side of the coin, there are companies that are barely making it and trying to control their prices would mean they would go bankrupt.
What we need to do (and I am 100% convinced that Kamala feels the same way) is to have a policeman (someone that is keeping a close eye on) monitor the situation.
There is a fine line that needs to be walked but then again, we have the Constitution and the 3 branches of government that prevent any one branch taking control. As such, it is unlikely that Kamala will be able to install such "price controls" that are bad.
On the other side of the coin, Trump wants to change the Constitution and given that the Supreme Court is in his favor, he might just be able to do it and that means that the 3 branches of government would not be able to stop him from doing harm.
