As a start, take some economics courses, intro Micro and Macro. (Check https://www.coursetalk.com/ https://www.class-central.com/ )

Actually the first book I'd recommend would be The Worldly Philosophers, a readable history of economics

A couple of more right-leaning books - Hayek, The Road to Serfdom https://www.amazon.com/Road-Serfdom-Fiftieth-Anniversary/dp/...

Friedman, Capitalism and Freedom https://www.amazon.com/Capitalism-Freedom-Anniversary-Milton...

Less right-leaning

The Marx-Engels Reader https://www.amazon.com/Marx-Engels-Reader-Second-Karl-Marx/d...
