This should be taught in high school. It's amazing that high schools teach nothing about how business works in a market society.
However I did learn to read, and a book on the bare basics of accounting is like 200 pages.
In the end, accounting means: how much are you earning, how much are you spending and how much taxes do you need to pay
1) Finance management
2) National and international law
3) Privacy
I kinda get tired of otherwise educated people having no idea what the difference between profit, revenue, margin, wealth, and income are. Also, the ones that exhibit such ignorance correlate with those who have disastrous personal finance behaviors.
