I think the definition of rich "successful" young teenager have to be said as building up his/her own fortune without the help of their family
A lot of stories out there
1) Lebron James
2) Lee Hom
3) Oprah Winfrey
4) Teh Hong Piow
5) mark zuckerberg - his family is rich ? his family help him built facebook?
6) jack ma
.... still got a lot more, the logic behind that TS try to mention is probably the opportunity that young teenager that come from rich family to be rich is greater but remember, there is a lot of cases out there where 1 generation is enough to kill all the wealth that is built by their father or grandfather
