You are more mistaken than those who are having the idea of teaching bitcoin to elementary school students. They haven't even perfected their reading and writing skills, how can they even think of getting rich?
If you'd knew those kids nowadays then you might get it that those ideas come at early age.
Specially when kids receive Smartphones to keep them busy. Typical 1st world behavior.
And the thing they do when they have their smartphones in their hands is use them for entertainment. I'm sure they will prefer to use these smartphones to play online games or watch movies. Just try to see how many games they download every day, and how much time they spend playing games and watching. At an early age like them, at elementary school, they are more focused on learning what is taught at school according to the curriculum and it's not that hard. In addition, they are still at that young age and still like to play and entertain. Even if there are children who are interested in Bitcoin, then it's probably only a small fraction of them. Or because they are only interested in getting money to buy snacks.
