You could always go with whatever person you see in your own society, that you think represents a different type of community. You can go with a lawyer, and how they are corporate and greedy, or a doctor, to show how much they care, and save lives on a daily basis, or a soldier, who fights and risks his life every day for his country, or a student, that is just trying to get up in the world by educating himself, or even a parent, that is trying to raise their kid right.
