National Socialists are not Fascists, I hate having to say this, but they’re Socialists, it is literally in the name of the party. And no, Fascism isn’t altruistic (altruism in my view is global), it is a very nationalistic view, and as long as Capitalism can thrive and social mobility exists then it is also individualistic. Altruism applies to all, Fascism applies to your countrymen and yourself and requires the betterment of the self for the betterment of society; meaning if an individual betters himself, his surroundings will inherently gain from that betterment, however you don’t better yourself with that in mind, you better yourself with self-betterment in mind (which is selfish).
"(Fascism) Does not believe in the possibility of “happiness” on earth as conceived by the economistic literature of the XVIIIth century, and therefore rejects the teleological notion that at some future time the human family will secure a final settlement of all its difficulties." Excerpt from The Political and Social Doctrine of Fascism by Benito Mussolini.
