Well I am sorry you were taught wrong.
A person who has study economics both from a philosophical and applied perspective would tell you, you have been given the wrong message.
It is sad because this false presentation is now having a backlash and people in the USA seem to be moving towards believing that socialism will work and will solve a multitude of problems, but it will not, because it has fundamental flaws in its premise about the nature of people.
Well I truly appreciate your candour, it helps me understand and very interesting because I do not live in the USA.
