Elites are naturally less racist, less ethnocentric, more cosmopolitan, than the lower classes. Elites can interact with *other* elites as peers. They don’t have to squabble over pieces of pie because they can make pie.
But the lower classes are justifiably racist, nationalistic, xenophobic, because they are in direct competition over resources they don’t create, infrastructure, services, social spending, jobs, and so on and so forth. Additionally, the higher impulsivity of the lower classes increases the friction that arise from differences and proximity. And they can’t afford to isolate themselves from these.
The classes can cooperate on common interests. And elites can cooperate with foreign elites. But in order for both of these things to happen, elites must give up treason as a sacred value, or they must be destroyed.
A people are less without their elites. But elites are nothing without their people.
