Stupidity on Family background

Izit a good or bad family background going to lead the way of their kid being grow???
A good family background izit going to born a good and full of future mankind???
Family background is something we as a child can't choose coz we got no right to choose which family to born from.. It's all set by fate, is this mean that a kid born in a bad or poor family going to lead their son to the poor generation too??
Why does human have to view a person personality and future based on their parent pass??
Izit so important a parent pass to him?
I'm sure a kid who is born in poor family can do better than those which born to have a good family background, poor family kids works more harder to get what they wan.. This made them more appreciate what they have than those rich kid..
Why as a person which have survive in this kind of rich and poor world can't just categorize a person by that person enthusiasm and work to carry on their life but have to categorize them from their family pass???
Izit there is a confirm statement that stated on their forehead saying that they will not success no matter how??
Is this stupidity human behavior must have on everyone mind itself??
I just dun understand how an age person view on us..
There is no explanation to be found by me, can someone explain it??
