re: Bernie Sanders just hates wealthy people

You could say that about most people in positions of power or influence. It doesn't matter, though. Being wealthy and coming from privilege also means that a person has a greater likelihood of getting a good education, work experience, or other opportunities to do good than others without such wealth or influence could.

You could argue that her position in life has made her more qualified.

Regardless, if she earned every cent she has or married into it, it doesn't matter. It's her legal property. That's something Marxists hate: property rights.
