Over the past couple of decades, a malignant form of historical revisionism has emerged on the American right. Led by conservative political commentator and convicted felon Dinesh D’Souza, the Right has peddled a convenient fiction: that the Nazis, because their full name was “National Socialist,” belonged to the Left, and that Adolf Hitler was a product of “statism” gone awry.

Nothing could be further from the truth, as investigative journalist David de Jong demonstrates in his new book, Nazi Billionaires: The Dark History of Germany’s Wealthiest Dynasties. According to De Jong’s thorough reporting, German capitalists supported the Nazis at every turn — and their legacy continues to this day, with the country’s economic elite still closely intertwined with Nazi war profiteers.

Many German billionaires, De Jong shows, are intertwined with the Third Reich, which extensively mobilized Germany’s industrial base and enslaved and murdered millions of Jews, Roma, and Slavs to deliver on the never-ending orders from the Reich’s military-industrial complex.
