Nazi social-security policy was its only propaganda claim grounded in truth

Evidence

Full employment is accompanied by an elaborate social-security program. The system developed by Weimar democracy has been streamlined and brought under authoritarian control. Unemployment assistance, health and accident insurance, invalidity and old-age pensionsthat is how National Socialism wins the passive toleration of the masses for the time being. Social security is its one propaganda slogan built on the truth, perhaps the one powerful weapon in its whole propagandistic machinery. — Rolf Wiggershaus, The Frankfurt School, 1191
