Financial Literacy not taught in a majority of High schools/Middle Schools, Why?

[Ashlee]

A big majority of mainstream high schools/middle schools don't teach students about the stock market and finances, why? (Most schools teach of things that students won't ever need in life; depending in what career field one would go into, but financial literacy seems to be very important.) Is the government trying to keep this valuable info purposefully "secret" from minorities? Could some one try to explain this to me. Thank you.
