Fascism is simplification for the emergent organisation of social status and relative rights in animal social groups. Pecking order of chickens, seniority, sex, authority. Whose interests get served first. Wealth and business, even in a democracy. In times of scarcity, only the front of the queue. First chick hatched. Evolutionary advantage is less energy wasted fighting for status every day. Result is human beings are status seeking freaks.

First sedentary city states needed slaves for agriculture labour. Walls helped keep them in.
