You're right, sorry, I have such moods. In fact, I have ideas. The problem is fear feeds competition, and competition feeds pollution. There needs more empathy between the people, and more education about each other... I thought the social scholars should figure out ways to increase bonding between cultures.
I had ideas which could seem strange, for experiment. Imagine you're told to eat a yoghurt, while looking at a foreigner eating a yoghurt. I think it could increase bonding, and empathy, ect... It's just a thought. (Don't make fun of my yoghurt.)
You say "fear feeds competition" but there's an opposing view by rhetoricians: Nothing ever gets better without at least the threat of competition. I don't often find myself defending competition, but there you go.
As to your empathic observation idea: go for it! One of my go-to heuristics is "symmetry of experience", that is, the more aligned the teacher and student are for example, the better the learning is. Symmetry happens often in communities and rarely in hyper-specialized institutions.
