I don't think they're trying to fix the system that made them billionaires, i think they're trying to fix the system that prevents other people from becoming billionaires, notably minority communities who are plagued by victim agendas spreas by leftist doctrine, for the most part.
I will say that their personal histories are scandalous, but hillary Clinton quite literally committed treason. The choice is obvious.
That's not to say someone committing treason makes them evil, i.e. Snowden, but the way in which she did is only conceited and vile. Traitorous.
