Listen to the libs on this thread, and you know what isn't taught...Civic Pride, and responsibility one has to community. Economics, and how big govt can take away personal freedoms, remove the health and welfare for all citizens. All the deficiencies in our schools can be attributed to a unionized educational system.
Oh...things like Freedom, Liberty, personal responsibility and self reliance and respect for individual property rights. That's in addition to teaching there are very unpleasant consequences for ignoring basic math and thinking you can consume more than you produce. Also that it's immoral and taxation without representation to spend the money of future generations.
