All men are created equal. Civic duties apply equally to everyone. Once people have met their legal obligations (say, paying taxes and obeying the law), any additional generosity is voluntary, not owed, so having more privilege does not automatically create greater moral obligations.
Say, I am beautiful and you are ugly. That’s my privilege. Do I owe more than you? No. It sucks for you. Sorry but that’s life. Stop whining and keep making the best you have with your God-given privileges (maybe you are say, taller or have more money).
