Ya. Lesson #1, not the final lesson but the ABC lesson taught to people who are just starting to learn. Later lessons will cover price concepts that make lesson #1 less relevant, such as that in realworld economics people are not all treated identically. Application of identical rules to all earners generally does not end well. That's why progressive taxation is a thing. A simple extension of progressive taxation is progressive handout/benefit schemes, money for the poor but not also to the rich. But that is probably lesson #10 or #12 and we are still on #1.
