So if this type of scenario will be applied at home, I guess this financial boot camp is never necessary at all. Yes, it can actually help but still the most powerful and big help are coming from the people around that surrounded the children most of the time.
I believe financial boot camp is still somehow needed because in some families even parents and siblings aren't enough knowledgeable about financial matters and in such cases it will be quite valuable for teenagers to join such boot camp.
I know that basic financial education is always thought by ones parents or siblings but when it comes to deep understanding of it then a teen should get encouraged to join a boot camp or these days it can be learnt by watching some good courses that are available. One can learn financial knowledge from home these days but still some guidance is needed.
