For the same amount of money, we don't all have to work as hard or produce the same amount of economic value, this is a true fact and it's ethically wrong. The economic reality of our situation affects every person on the planet so it affects everything. It's vitally important that we all understand how the system works even if explained in such hand-wavy way.
It's no coincidence that they don't teach this in schools. You'd think they would want people to know how money is created; after all, everyone spends their entire lives working for that money but we know nothing about it - The elites who control the banks don't want people do know because people would be able to see so many issues.
Isn't it strange that in school, we learn Maths, Physics, Chemistry, English, Geography, History... The arguments used for teaching those subjects is that they provide a good foundation of knowledge for all citizens... but when it comes to one of the most important subjects in our lives which affects every single citizen, we don't know anything about it. We all come out of school having a pretty good idea about how gravity works but we know almost nothing about how the financial system works (even though knowing about the latter can be used to our our advantage). It's no coincidence. If the majority of people knew, the current system would collapse and be replaced by something better.
