Also, I wonder if OP and the people supporting this idea have children and have talked to them, and listened to them say what they want? Or is this just the thinking of people who don't have children, don't have experience and don't even know how to start raising children? We should not try to impose our thoughts on anyone, especially our children.
Let's just assume that it is both. There's no problem for someone who doesn't have a kid and tries to suggest something like this and the same goes for the actual parents that haven't heard of this idea. Let's be open-minded with ideas that can enrich someone's ideas and knowledge towards something like this topic for financial literacy. Based on this study:
Financial Literacy Around the World 33% percent are financially literate and this only covers for the adults only and if converted into count, the study says that it's around 3.5 billion globally that does lack of financial understanding. So, if someone tries to give a good idea for others to have more understanding towards financial matters, be open to it and embrace the potential learnings that can be extracted from it whether it's theoretical or in actuality.
