They can all cause systemic inflation of the type we're talking about - because remember, this thread is about the type of inflation caused by tariff policy.

I don't grant that point. "Inflation" is commonly defined as "a sustained increase in the general level of prices for goods and services, measured as an annual percentage increase. It reflects a gradual loss of purchasing power, indicated by a broad rise in prices over time."

Tariffs on this good or that good don't do that. Only an oversupply of money does.

If somebody wants to argue the price of X or Y is affected by tariffs, then that engenders a discussion about the willingness of importers to either absorb or pass on the cost of tariffs knowing that competition in a local market may be participants that aren't paying tariffs at all. As opposed to inflation which is a systemic condition of the economy.

As far as your point about teaching atomics in chemistry, you're a bit off. The point of teaching Rutherford or Bohr isn't to say "Atoms look like this" it's to

a) share an appreciation for the evolution of the field of chemistry over time, a field that expanded into what we know today as Quantum Mechanics, and
b) introduce to students the principles of protons, neutrons and electrons to prepare them for lessons in molecular bonding, relative electronegativity and chemical formulas.

Understanding those concepts allows a student to better grok why certain elements are more reactive to others and why certain compounds form the way they do. Basic chemistry is the foundation for organic chem, combustion, catalysis, polymerization and a whole bunch of other things.
