In my experience as an American (32 years) most Americans fight hard for the rich. If you tell someone: "Their rich because their parents were rich." you will almost always be met with resistance and it usually comes from an individual of a lower class. I don't know why it is but that's just how it is. It was amazing to see so many poor people voting for Trump and then when you tell them a few facts about Trump and how completely opposite his life has been to theirs they not only resist it but in some cases get very angry.
