In this interesting video (about 10 minutes) Rifkin discusses the discovery of our natural ability to empathize.

He points out that we do identify with others and empathize; we are basically good. He talks about early man living in tribes and empathizing with fellow tribe members, but when religion grew we then identified with and empathized with fellows of the same religion. The same transition took place when nations arose and we identified with and empathized with countrymen. He sees the next step as identifying with all of humanity as trade, travel and ease of communication progresses.
Of course those of us who see peak oil as a turning point might disagree about his view of a future with expanding globalism. While he emphasizes the positive side of feeling empathy toward others with whom we identify, I see the negative side. We easily go to war with other nations because we do not identify with them and do not feel empathy toward them. And before nations, we did not identify with people of other religions and easily killed them. And before religion, we easily engaged in tribal warfare for lack of a common identity and empathy.
As peak oil unfolds and economies enter long term contraction, I think the pressure will be for nation states to collapse. If we congregate around religion instead of the nation, then that will replace national identity with the potential for religious wars. And if we congregate based on tribe (race) then we will have the potential for tribal warfare (race war). And in reality, all three of these identities seem to me to operate simultaneously. We have religious divisions within some nations that even erupt into violence. We have tribal warfare today within some nations, and look at the racial division that exist in the US now, white, hispanic and black.
The potential for conflict based on lack of identity with others and lack of empathy for others seems very high in a future that has resources adequate only to support a fraction of the current world population.
