Classes on cultures — cultures around the world and in our own country. If we had such classes, we wouldn’t have the world crisis we have now.
Added to culture, geography. American students suck at geography and only a smidgen of it is taught, usually in elementary school.
Art. More art. Better art. Street art.
Real writing classes. More intense writing. How to write, punctuation, creativity in writing. Texting and social media kill the art of writing.
Relationships. How to speak properly to others, how to speak in opposition without dissolving in to vulgarities and screaming, how to resolve disagreements, how to persuade, suggest, and influence without belittling, bullying, and controlling.
