I am teaching you the root of economics ...

it may not be legal for you to learn this in any public school system ... so it may only be legal for you to learn it here ...

assuming it is legal to do so ...

 many times it is not legal for your family to help another family after that family has helped your family??? in many cases, another wards someone from government will be required by law to take away from the family that you algebraically economically gave to ( sorry for not being able to communicate it correctly, my communications skills are lacking )

which family have you helped today to solve an algebraic economic problem in a tactful way, who has the skills to algebraically economically legally help your family solve a problem in a tactful way ???

government could solve this problem with a government run economics education class, I have still yet to find it ...
