The question of German industry and Hitler was the background to one of the nastiest disputes in recent American historiography, over a book by David Abraham which agreed with you, but was riddled with errors. Most of them were trivial sloppiness (ranging from minor cite errors to passing off paraphrases as direct quotes), but a few were quite serious (you do NOT cite non existent documents or insert/remove a negative to make it look like a key primary source says the opposite of what it really does to make your argument more convincing). Henry Turner, a very eminent historian at Yale who has specialized in the subject launched a campaign against Abraham and succeeded in getting him drummed out of the profession (he had gotten a TT at Princeton, lost his job, went to law school and is now a law prof). There was a strong political subtext to the mess as Abraham is very left wing while Turner fairly right wing.

In any case, if you want serious reading on the subject from opposite perspectives, you can try the revised Abraham The Collapse of the Weimar Republic: Political Economy and Crisis (don't read the first version) or Henry Turner's German Big Business and the Rise of Hitler
