Yes, I vaguely remember that I signed up for economics class because it was an alternative to something else, and also I liked the teacher well enough from 11th grade history that I thought it could be interesting. That said, I do not remember any rule requiring everyone in that class to register as Jewish, nor do I remember anyone keeping track of who was or was not Jewish in economics class. It was just a class where I am supposed to be learning about how the economy works, as per "money makes the world go round." Without money in circulation, there just is not going to be anything else to say about economics class. The economy belongs to everyone.
