I wouldn't say that, actually. Germany's recovery was primarily fueled by massive deficit spending on rearmament and social programs. Keep the people pacified, bootstrap from the tiny military allowed by Versailles up to something world-class, then take over Europe and Asia. Not sustainable at all, and I think it's really debatable whether Hitler deserves any of the credit anyway. His role was more or less to turn on the money tap and tell the Prussians to tool up, which they did very happily and effectively because they were Prussians.
