Unfortunately, not all schools have even Economics as the subject. The government is not interested in making their people financial free as they will not have tools to manipulate people then, so they don't want to have us aware of investment. On the other hand, if countries adapt crypto as a national currency, they will have to teach people how to use it.
I guess almost all school teach economics, but a different kind of economics. There are various forms for economies to be operated and depending on what the government wants their education system to teach people, they will put in on the agenda. Certainly in countries where power over the people is crucial to the government, Bitcoin will probably not be part of that agenda.
