HERE'S THE SAD, UGLY TRUTH:
Virtually all major industries in Germany, as well as a good number of them in Europe, which have been in business throughout most of the 20th Century and remain active today, were actively engaged in support of the Third Reich.
Virtually all of them.
BMW, Porsche, Daimler-Benz (Hitler's personal vehicle was a Mercedes), Krupp, Siemens, Anschutz, Weirauch, (firearms), Bayer (ever taken an aspirin for a headache?), Hoffritz, Solingen (cutlery, knives, swords), Anschutz, Sonor & Lefima (percussion instruments), etc.
You must understand, fellow JTF members, that long-established German industrialists, regardless of their personal opinions or politics, had the options of remaining in their German homeland and continuing to run their businesses, or literally running for their lives and sneaking out of their own country.
In addition to the industrialists' lack of options, [do any of you know any CEOs who closed up their industries and left the U.S. because they disagreed with the Clinton Administration?], the Third Reich quite literally took a bankrupt and morally broken nation which was humiliated and full of despair, and restored it back to a "full steam ahead" world power in just a few short years. The heavy industries, agriculture, as well as all branches of the sciences, were suddenly working overtime and prosperous. Unemployment virtually disappeared. A country which had had its military stripped to nothing, was almost overnight in full production of the mightiest war machine, with the best equipped and best trained forces in the world. Hatred for the Jew not withstanding, the giants of German industry and production quite literally saw in Adolph Hitler a "messiah" who made promises and kept them as well. Like their counterparts today in America, German industrialists were concerned with "the bottom line", "growth", "volume", and "higher profit margins". The German Fuhrer was the first German leader in modern times who kept his word to those who put him in power.
*I offer this overview not as a defense of the Nazi Reich, but as an example of normal human behavior observed in all people, regardless of nationality--If you don't know where your next meal is coming from, and your government and economy are virtually nonexistent, your currency worthless beyond worthless from hyper-inflation, then it is most likely that you will follow the first person or group which proves able to completely reverse your misfortunes and make you and your country wealthy almost overnight.
