That's possibly every state in the last 400 years, with the possible exception of the soviet union and Maoist China, and those exceptions are arguably just a technicality.

Maoist china certainly and famously murdered many rich people. It's true that the state that emerged had deep corruption and that life remained difficult for the poor, but murdering rich people is an allegation difficult to deny.

I think what's different is that we actually have democracy, yet for whatever reason, the masses of poor people keep voting for governments that overtly and openly only care about rich people.

You forget the French, who inspired Marx's exhortations to practice "revolutionary terror," the "only way," [0] with their own public executions of the rich [1].
