I would oppose the idea of children as young as 7 years old taking finance courses or financial bootcamps like your idea. In my country, 7-year-old children have not yet finished first grade. Is it too much to force a child who has not yet mastered basic addition, subtraction, multiplication, and division to know about finances? Why can't we give them a beautiful childhood? And what will ensure that forcing children to learn about finances early will help them become rich people later?
I am not against the idea of teaching finance to children, but I think it is not necessary to teach it too early when children have not even finished first grade.
Having a financial boot camp is actually a good idea but only to those who are ready enough to absorb all the ideas and information.
