Most countries dealt with their internal fascists during the 20th C without mass slaughter.
France, Australia, the UK, etc; we all had fascists in the thirties, and we’ve still got 'em now. But they’re mostly a small and relatively powerless group (although the recent resurgence of Le Pen in France is worrying) and are held in justified contempt.
Blaming poverty for fascism is a mistake, IMO. Yes, economic stress tends to encourage political extremism, but the genuinely poor usually don’t go fascist; they go communist.
Fascism appeals to those who are fighting to retain their privilege, not to those who never had any to begin with. It’s a middle class pathology.
