Oppressed? No. Rich people are just people, shocker. Some dont give a damn about the poor, some give tons to charity, some in between. Of course rich is already in contention, I know a lot of people here think 200k a year is rich which still makes me smile.
The point does stand though, that you must be sure to be appropriately chaste about your wealth lest you become the bad guy. That can be at any income level over the national average. If you make 75k, the guy making 22k thinks you're rich and you too can be the bad guy! Once you become the bad guy, your best bet is to be quiet because if you complain and/or fight back, well now you're just the rich guy complaining and people will say things like "Are... are you suggesting that the rich are the oppressed, and the poor the oppressors?"
So, make sure you say things like you got your money by luck and thanks to other people. Give a lot of it away, make a show of your compassion for the under privileged, that sort of thing. Even if you dont feel that way, insulate yourself. Then, when no one is looking, do a drive by on a welfare office with your diamond plated M-16. Rich people do that kinda thing all the time.
