To get us started on this one, I send you to this 2016 article at The Guardian. Goebbels' 105-year-old secretary leads the interview with this:
The only thing you can say about Goebbels is that he was an outstanding actor.
Before we go any further, I want to be sure you understand what we just uncovered. Joseph Goebbels married Magda Quandt in 1930, when she was 29 and he was 33. Her previous husband was a billionaire, one of the five richest men in Germany—and he was heavily tied to many military contracts. One of his three sons was hers: Harald Quandt. So she remained tied to that family after the divorce. And yet we are supposed to believe Joseph Goebbels was an editor and speaker for a workers' party? This billionaire's ex-wife just happened to marry an up-and-coming speaker in the Workers' Party? Do I need to remind you that workers were the political enemy of the billionaires? The Quants are known to have used slave labor in their factories. See the 2007 German documentary Silence of the Quandts, shown on German public TV station ARD. So the Quandts would not have supported the planks of a workers' party, would they?
