As for me, kids learning at an early stage about investing is a good one. It is going to teach them how to be wiser with money and the rest about getting rich, they'll discover that at their right ages.
Or it might turn kid into unhappy kid if all he is thinking about and spending money on is investing. Other kids buy toys and sweets, but this kids only invest and envy other kids. And what would little kid invest into? Someone told him that "this new toy will be cool in 10 years, or this game will be in hot sales" and he will invest all money in that. Kids trust everything. How can they do a serious research at that age? You will say with a help of a parent. But it will turn into parent doing all the work, but the kid only gives money. This isnt learning and investing, this is giving/borrowing money to a parent for certain time.
It is good that they know what investing is and what he might achieve with that. But forcing to do that or insisting that "if he would not do that as early as possible, then he would never be rich" is wrong. Parents would better put more effort on motivating kids to study more at school or university.
Well, that's what you think about kid learning investing too early which is also possible. But this modern day is different. More kids want to learn something new and they've got more source of information nowadays.
I don't know, but I would not disagree to what you're saying because that's your opinion and it's possible to have those kids with that mindset.
But I wouldn't explain further about a kid learning about investing on their very young age but it's beautiful that we do have different thoughts about it.
