Since then I've asked several people to tell me one thing they learned in high school chemistry; I usually get silence as an answer. I actually didn't expect it to be that bad. Of course the point of chemistry is not to make you a chemist and it's purpose is to teach you another way of thinking, the scientific method, to expose those who love chemistry to their future career, etc., but why not spend more of that time on things that you will need to know?
Here's my list, please feel free to add you own in the comments section, I'm curious what others think should be on there.
How to be a better consumer - related to finance and research
How to find a job, write a resume, dress for an interview, how to act at an interview

A class teaching you how to research anything. Also, how to read a research paper and where to find them
Basic circuitry, computers, IT infrastructure

The new variable in the equation is of course the internet. Not long ago books were prohibitively expensive. If you go back far enough in time a single book could cost more than the common person could afford. Knowledge was hard to attain and spread. The barriers to entry have been reduced to the point of a laptop or tablet and a small source of power, and indeed to people in rural parts of the developing world this is the cost of their tuition. I've always found that I learn best when I'm teaching myself (really just reading lot of articles online), and increasingly that may be the mode by which many people learn. The kid in the video below takes this to a whole new level. And yes, it's worth your time:
