I would never hate somebody for being rich. That would mean I might have to help myself one day when I also earn my way to that honor.
The only thing I might hate about rich people is when they use that wealth in a manner that is disrespectful of others. I have known many people who have amassed great wealth who still are well grounded. On the other hand I have also dealt with many that believe they are gods gift to the world and that the rest of us are only here to act as their servants.
