This is a capitalist society. Learning economics can help you better understand business models and society, so I think this is a very important subject. In the future, people can learn the blockchain in school.
Introducing blockchain in school can be very helpful as:
1) It is recent technology and thus students will be able to learn something new and benefit from it.
2) If students learn the art of trading like researching about good coins, it can provide them monetary benefits as well.
