"Us vs. Them" is supposed to come after the "Me vs. Me" battle is resolved. After all, how can one successfully interact with others if one has not yet mastered the self? In this atomised socially darwinistic culture ever increasing proportions of the population fail to win "Me vs. Me" and are thus not psychologically mature. The advertising industry makes more profit from immature adults than mature ones. However, to become the best version of yourself, to have proper self control, to have both command of your empathy and logic, is vital to the formation of society and cohesive culture. When you have done this you will be ready to convert "Us vs. Them," into "Us and Them," and then onwards to a sense of "Us."

Cohesive society and culture comes from healthy individuals who are able to act in empathic and cooperative ways. The macro-level is always built from the micro-level (as in chemistry, as in biology and ecosystems). Measures that seek to contain macro level society and cultural issues without focus on the micro level are playing with symptoms rather than cause. Or put simply, free school meals are more effective for societal healing than riot police - though as a society transitions it will need both attention to symptoms and cause.
