I've been thinking about this for a while now, and the core of the divide seems to be that people divide themselves into groups and seek advantages from one another as if they're playing a zero sum game. That may or may not be by design, but it's what I believe to be the "how" of it. The only solution that's ever worked to turn that around is sacrafice. People need to start intentionally engaging in "losing" propositions to win hearts and minds to a cause. It's only by delivering gifts that you can turn a competitive game into a cooperative game where everyone wins together. If everyone insists that they win first, then you're stuck.
