Agreed, and the intention here isn't to block any particular policy outcome, it's to ask that you narrowly scope your tools to what can work, instead of being the 20th failed attempt at price controls or tariffs. (And Econ 101 will teach you when tariffs can make sense, too)
I was an econ major, and a lot of the lower level courses were required for business majors.
It was genuinely shocking how many people from the latter group just could not understand the absolute basics of supply curves and demand curves.
The upside is that I was able to help them understand it by offering tutoring, where I was in limited supply, and there was endless demand for my services!
Studies consistently find about 20% of Americans are functionally illiterate, depending on what is meant by functionally illiterate. Typically this means that they can read, but frequently cannot grasp the meaning of what they read.
The US is actually pretty illiterate compared to peer countries.
