if i could go back and re-pick my high school classes, i would definitely have opted for home ec electives.
all i got in school was a trimester of home ec (which included sewing and cooking) each year of junior high. it was part of the core classes everybody took.
We also have a epidemic of just throwing shit in a landfill and getting a new one.
I could give a shit if someone wants to eat chicken nuggies for every meal. I care more about landfills piling up trash that could have just been repaired or reused.
We have what 70% of the US population overweight or obese. That's the problem of our times.
Not to mention that fast fashion means we go through clothes before they are worn out, the gain is on wearing them until they worn out. When it's threadbare sewing will not help. Teaching sewing is not a good use of time, make the best use of the resources we have.
You do realize that teaching people to cook does absolutely nothing to keep people from being obese, right? I cook all the time, still over weight. Cooking fresh food does not equate to a healthy diet and being thin. People's over eating, and diets don't really affect you.
Plus, you can't force shit like this on people, they have to want to do it. I could eat healthier, sure, but I'd truly rather die a few years younger than to have wasted my life eating beans, rice and basic meats like you are suggesting.
