Sky diving into the ocean

In my opinion it seems like societies generally focus on the positive affects of a group being in power (in regards to that group and not what it does to others), and the negative affects of being a group that is not in power? But, just because we generally talk about those sides does not mean there are not others. For example, what are negative affects of a group being in power? What are positive affects of a group not being in power? If this was recognized by both types of groups would it change anything? Just some stuff to think about.
