at my school they did, and i guess other schools do that as well!

They teach things about bonds and money, how it is just created as numbers in banks - at least at my school they did!
It was not called "bad" and it was not about the slavery behind it, but it revealed the process of how money is working, and how banks can create "bank money" for loans.

An example that i remember from school was:
"If you go to a bank to get a loan of 500 000 to buy an house, the bank did not to have these 500 000. Its enough that the bank got the house as leverege, so the bank can create the money for the leverge as called "bank money"."

I did not remember which class that was but i guess it was "oberstufe" like the germans call it.

So schools doesn't seem to be that bad at all

(Sry for my bad english, but i guess i missed some classes there, in school english doesn't seems to be that important at all XD)
