The parent poster wrote "poor people who have nothing more to hate on rich people about than that they have money", which sounds like well-founded animus to me.
Let me make sure I understand, because I fear we may be talking past each other.
Are you suggesting that the simple fact that one has more money than you is sufficient to justify animus?
(I'm happy to discuss the rest of your post once we clear up this particular point; it seems fundamental.)
