That said, there is no way that I can see myself doing it in the context of a high school or college.
High schools (at least the several that I have subbed at, and I have a couple of teenagers, so I've been on that side of it too) are really crappy "Lord of the Flies" kinds of places.
Colleges are better, but there are similar structural problems to being a musician: it's basically no pay for a big sector of the population, plus you still have an institution around your students.
The best model that I have seen is private students; my wife has 40 violin students (plus her general business of being a musician, plus teaching with a couple of local youth orchestras) and makes a very good living.
There is no reason that you can't apply the same principles to teaching any subject. I asked around, and there was a high demand for folks who wanted me to teach their kids how to program. I imagine that if there were a bigger population, I'd be able to find enough folks to put together seminars on the same stuff I was teaching at the university.
At that point, setting your own curriculum is part of the job and not a fantasy.
What is wealth? Things people want. Money = wealth not because it's directly useful but because people want it so you can trade it for things you want.
Why do people want Money? Taxes, and loans. If you sell stock to buy a car, you need extra money to hand to the government. Further, if you have a mortgage or credit cards you need to come up with cash on a very regular basis.
Then build on this:
What is the demand curve? Different people are willing to pay more or less and buy more or less of the same things. ex: 3rd car.
However, you would be much better making this into a book than teaching a class. As again Econ 101 is setup so people can do a lot of math in Econ 301.
Common people should know the philosophy which shaped the government thinks about their lives and productivity.
Yes econ is not a true science, because it is mostly conjecture supported by handpicked data, but at the same time, it is the only template we have created to think about the complex interactions in the competitive marketplace.
The power of the competitive market is the foundation for all capitalist action, economics is a way to understand how markets intersect and interact.
Do a search and: The demand curve is a graphical representation of the relationship between the price of a good or service and the quantity demanded for a given period of time. In a typical representation, the price will appear on the left vertical axis, the quantity demanded on the horizontal axis. -This means nothing to most people.
"What is the demand curve? Different people are willing to pay more or less and buy more or of the same things. ex: 3rd car, water for a bathtub vs water for a swimming pool." -Sounds like something you might recall in 10 years.
I am all for talking about the laffer curve as more than as math. You can also talk about it as society breaks down and a black market grows. It's still economics as it relates to society it's also meaningful to people.
For comparison CIS 101 is often this is how you use Excel and somewhat useful to most students, but also not really a foundation for a CS degree.
I feel the math should be used to prove the philosophical points. It's rare that the math actually improves understanding without a novel hypothesis behind it.
