Those of you who came here for dark humor and not politics, I apologize.
I want to preface this by saying that I'm not a socialist. However, I feel the need to point out that there are differences between democratic socialism and national socialism.
Democratic socialism aims for popular control rather than centralized state control. It stresses concepts such as worker's self-management and workplace democracy. The intent is that workers would have more say in how the economy is run, hence democratic socialism often overlaps with the ideology of direct democracy. Whether or not this is a realistic or attainable goal is up for debate, I get the impression you think it's not, that's fine, I'm not trying to start a keyboard war here.
Conversely, national socialism puts the emphasis on a totalitarian state which controls the means of production. Yes, it is socialist economically, but unlike democratic socialism the workers would have little if any say in affairs. In this system a one-party state and its officials control all aspects of said socialist economy.
Nazi German economic policy was actually not very socialistic. In name, yes, but not in practice.
"The Nazi government developed a partnership with leading German business interests, who supported the goals of the regime and its war effort in exchange for advantageous contracts, subsidies, and the suppression of the trade union movement.[10] Cartels and monopolies were encouraged at the expense of small businesses, even though the Nazis had received considerable electoral support from small business owners."
