I hate to suggest this....but I’d basically toss out American history for twelfth grade students in high school, and just have an entire year of study on economics...both at the personal level and the public level. I think if you laid out the problems of borrowing $50k from some government agency or bank....to go off to college, then most would decline the opportunity, and just study locally with the community college.
This would also bring up discussions over how a town borrows tons of money to build something....that they might not really need. Taxes could openly be discussed, along with personal finance and credit cards.
Perhaps skipping sexual studies instead of history would be wiser. The lack of an understanding of history is a root to this mess.
I would do exactly the opposite. Throw out economics and teach American history and the Constitution for the entire year.
As it regards government and the economy, one has nothing to do with the other. Business is not the business of the Federal government. The entire premise of our Constitution is that the citizen may do as they please as long as they harm neither the person nor the property of another.
If we first educate students that the Constitution did not empower the Congress to legislate anything other than the “herein granted powers” referred to in Article 1, Section 1. Learn that first and they will learn economics in less than one week. The economy, sans the government, is supply and demand, risk and reward, that’s it.
