At the point with investment I was lost. Children should learn to be patient (saving money) and prepare for bad situations (saving money). That’s enough.
When older we can teach them what capitalism considers as investment. Capitalism is a longer word for greed. Money doesn’t work. Employees do. Customers pay. Both suffer to make greedy persons rich.
Give them a piggy bank. Teaches the concept of preparation.
Even saving can be seen as greed. Someone can focus too much on accumulating for themselves. Both investing and saving can be seen as preparation.
To avoid things becoming evil, you just need to make sure that your interactions with other are cooperative and not zero sum, and not all investments are zero sum.
