I think it is really inappropriate to blame someone who was born into a rich family or was born to parents who were already rich as you mentioned. Because basically everyone in this world is always trying to get rich by always relying on the abilities they already have, so it's really not worth blaming rich parents or a child born into a rich family.
Because as long as the child can become more independent and learn to be responsible by taking advantage of every convenience that already exists in his life, then there is no one to blame for this rich condition. Moreover, I am also quite sure that not all rich people's children are spoiled and also not all poor people's children are hard workers, even though on average poor people's children do have to work hard even though they are forced to endure pain. So don't think that to be good and independent every child must be born into a poor family.
Your family's wealth at birth is just the beginning; it's not the end. We don't always think about the unique stresses and demands that people born into wealth have to deal with. They have trouble keeping up or going beyond a heritage, don't they? Dreams aren't always made of silver and gold. Let's switch our attention to the ideas of independence and money management. Rich people can give you tools, but does that mean they are smart? Not all the time. How well you handle and make the most of these resources is the real test of your personal growth, no matter how much money you have. Money can help you get ahead or hold you back; it all depends on how you think about it, right? As for the idea that hard times make people stronger, yes, they can. But not everyone agrees with it. Rich kids have been great examples of duty, and poor kids have had a hard time with the same thing. In the end, things happen to us, but the decisions we make define us
"Money can help you get ahead or hold you back" I'm quoting this for reference purposes. Consistent thoughts on money has removed the idea of reading, and being joyful in the life of many people. Rich folks bother a lot on difficult problems, which money isn't a part of. Convincing the mind that money removes problems is one example of money holding people back. Families work all day to raise money to better the lives of their children but fail to give adequate home training. Money won't be there to solve such a problem. We can't have it all, and the speed at which it finishes is alarming. Why not hold on to the little things that we can control and benefit from in the future? The children of the rich, in this context, are those who can afford to buy a car and pay rent but still work late hours each day. Such kids miss the parental love and care, yet seem to get anything they'd need as kids; toys and cash. Growing up, the demand increases, and the wealth of the parent decreases. The parent's love and care weren't there initially, and the child or kids grew up with little or no much time spent with their parents. They only believed that whatever they asked of their parents, they'd provide.
Moving forward, they begin to demand more expensive things, and the parents, both, try to deliver them instead of cautioning the kids that money isn't treated in a way like that, where they keep buying expensive products. Keeping calm on such matters, the parents want to maintain a rich lifestyle for the kids. With no financial advise or business left for the children. The parents only work hard and earn high paychecks, to meet up with such demands. When the parents depart this earth, those kids despite having all the money could buy to look rich in the eyes of the society. They'll be far backward from the ideas of managing funds. Like a hammer, money has broken them and weighs in a bigger problem that holds them back. Practicing similar behavior inherited from their parents, the child will continue reckless spending of money as a habit. Until money is gone, and the family goes bankrupt. Many years would creep by before the family would bounce out of poverty. This type of person suit the context of Op's thread. As for the Upper class, 1%, money doesn't dry in the family, because the kids of such men are well groomed on the ethics of financial management.
