We’re in an obesity epidemic and most people don’t know how to cook even very basic meals.
Make space for it, squish other classes if you need. Make it mandatory, everyone has to take it. Maybe even ongoing through multiple grades.
Edit: Rice, beans, and even basic meats are cheap. To eat healthy you don’t need your meal to be 100% Bell peppers and tomatoes.
Do they not teach home economics anymore?
Also, a lot of finance applicable stuff is found in math. It’s no coincidence that the majority of people don’t know finances and the majority of people also brag about how much they ignored or hated math class.
