Is metaphysics about how you want the world to be? Just because you want a universal ethics doesn't mean there is one. However, I think there is a universal ethics and it is based on the fact that people can gain more by forming bigger groups with a greater division of labor. It's wrong to enslave a neighboring group because you gain more with less risk by forming trade relations with them. However, I have seen that these considerations don't seem to matter that much in the real world (at least in the short term), so maybe it's better to be part of an in-group that exploits everyone else and there is no universal morality. Karma that works too slow doesn't punish these acts quickly enough for people to care about it. If we had a way to make Karma work faster then people would have to think about this kind of thing a lot more though.
