The three books I would recommend to anyone trying to read up vaguely conservative thought are below, and I'd recommend them to college freshmen, not middle schoolers:

Starship Troopers

Why patriotism is necessary for a state to function.

How to be a Conservative

Basic concepts of don't print money, don't destroy traditions, upholding tradition takes work, don't destroy laws, and wanting all of these things is cool.

Vision of the Annointed

What the enemy-there is one, it hates you-is doing, and how to spot it.

I'm not even sure of the value of teaching free market economics other than as a jumping off point. At this point now the only people who still think the market is free are shitlibs. The rest of us know better. Teaching inflation should be heavily underlined that the banker printing the money is unaffected by the effects of inflation but the borrower spending the money is not - and that the banker is never neutral, and has political interests.

This is a world where the elites just flip presidency switches for the UK and US from red to blue at will, and switches global lockdowns off and on at will. given the choice between money and power, the person in charge of printing money will always burn through the money to protect their power. Basic economics will never teach you this.

You are much, much, better served figuring out when the Democrat Party are going to sperg out and get the Fed printing, and understanding the psychology of the average Boomer and how they think the world works than you are reading dcf charts.
