Most rich parents don't put more effort into training their kids well. It's why we have so many of them that are spoilt brats without any good manners out there.
I see a lot them online on different social media sites where they talk like fools without brains. I just try as much as possible to avoid getting into exchange of words with any of them because it's useless talking to them.
Money always have a way of making people to misbehave. This is the reason why kids that are born in a very rich family are always spoilt like brats because their parents give them almost everything they want. This makes them to behave in a very weird way.
