Conservatism: Morality is for the political and economic elites a tool with which to oppress the poor. If it ever came down to a simple test of force, the poor would easily win, both on an individual scale and a collective one. That's why right-wing parties always harp on and on about morals and tradition, because the only way they can maintain dominance is by creating a bloated sense of obligation.

Fascism values two things: power and uniformity. These two things inevitably conflict, and to maintain the unearned sense of self-respect that Fascism appeals to, they must choose uniformity.
